The automotive industry revolutionized the definition of a vehicle in terms of safety, comfort, enhanced autonomy, and internet connectivity. With this trend, the automotive industry rapidly adopted automotive Ethernet such as 10Base-T1, 100Base-T1, and in some cases, 1000Base-T1. 

Faster Speed (than CAN-FD), Scalability, embedded security protocols (like MacSec), cost and energy efficiency, and simple yet redundant network made Ethernet an obvious choice over CAN(FD) and FlexRay.  

Ethernet 10Base-T1 

10BASE-T1S is defined under IEEE with 802.3cg. The S in 10BASE-T1S stands for a short distance. 10BASE-T1S uses a multidrop topology, where each node connects to a single cable. Multidrop topology eliminates the need for switches and, as a result, fewer cables/less cost. The primary goal of 10BASE-T1S is a deterministic transmission on a collision-free multidrop network. 10BASE-T1S cables use a pair of twisted wires. As per IEEE, at least eight nodes can connect to each, but more connections are feasible.    

The Physical Layer Collision Avoidance [PLCA] protocol ensures that it uses the entire 10 Mbps bandwidth. In 10BaseTs, Reconciliation Sublayer provides optional Physical Layer Collision Avoidance (PLCA) capabilities among participating stations. Using PLCA-enabled Physical Layers in CSMA/CD half-duplex shared-medium networks can provide enhanced bandwidth and improved access latency under heavily loaded traffic conditions. The working principle of PLCA is that transmit opportunities on a mixing segment are granted in sequence based on a node ID unique to the local collision domain (set by the management entity). 10BASE-T1S also supports an arbitration scheme that guarantees consistent node access to the media within a predefined time.  

The 10BASE-T1S PHY is intended to cover the low-speed/low-cost applications in the industrial and automotive environment. A large number of pins (16) required by the MII interface is one of the significant cost factors that must be addressed to fulfill this objective. The 10BASE-T1S "Transceiver" solution is suited for embedded systems where the digital portion of the PHY is fully integrated, e.g., into an MCU or an Ethernet switch core, leaving only the analog portion (the transceiver) into a separate IC. 

Ethernet 100Base-T1/1000Base-T1 

100Base-T1 and 1000Base-T1 can be used for audio/video information. With Higher bandwidth capacity, 100Base-T1/ 1000Base-T1 paired with AVB (Audio video bridging) can be used for car infotainment systems. 100Base-T1/1000Base-T1 paired with time-sensitive networking [TSN] protocol can be used to fulfill the automotive industry's mission-critical, time-sensitive, and deterministic latency needs. 

 PTP Over MacSec  

With today's automotive network, all the Electronic Control Units connected require timing accuracy and network synchronization, Precision Time Protocol (PTP), defined in IEEE 1588, provides synchronized clocks throughout a network.  While maintaining the timing accuracy for mission-critical applications, protecting the vehicle network from vulnerable threats is mandatory, and PTP over MacSec provides the consolidated solution.  

With the availability of the Cadence Verification IP for 10/100/1000BaseT1 and TSN, adopters can start working with these specifications immediately, ensuring compliance with the standard and achieving the fastest path to IP and SoC verification closure. The 10/100/1000GBaseT1 and TSN provide a full-stack solution, including support to the PHY, MAC, and TSN layers with a comprehensive coverage model and protocol checkers. Ethernet BaseT1 and TSN VIP covers all features required for complete coverage verification closure. More details are available in the Ethernet Verification IP portfolio.

Does anyone know how to not include a pbar in a constraint manager analysis? I have some relative delay constraints applied on a group of differential nets. When I analyze the design these all show an error. If I delete the plating bar from the design they are all passing. The plating bar gets generated on the Substrate Geometry / Plating_Bar class. I understand that I could just delete the plating bar to verify the constraint but the issue is when I archive this design I would like it to be clean meaning it is in the final state for manufacturing AND passing all constraints according to design reviews.

Anyone have an idea? 

Thank you!

Starting from SPB23.1, a new option, Allow DRCs to surrounding metal, has been added in the Etch-Back form to allow DRCs to the surrounding objects. form to allow DRCs to the surrounding objects.

The Allow DRCs to surrounding metal option lets you see and adjust objects instead of the current behavior, which sacrifices the width of the mask for the trace.

• When this option is turned off, it maintains the EB mask to another object clearance.
• When this option is enabled, it keeps the EB mask to the EM trace edge clearance and shows a DRC if the EB mask to another object spacing is out of rule.

Hi，

There are mang components in BGA ball side of flipchip package.

Are there DFA check space of compont body or pin soldermask to BGA ball or BGA PAD or bga  soldermask in allegro APD?

I only find space of compont to compont in APD DFA. 

The DBDoctor application checks the database for errors and other problems, and presents a report about them. DBDoctor supports .brd, .mcm, .mdd, .psm, .dra, .pad, .sav, and .scf databases.

DBDoctor can:

• Analyze and fix database problems.
• Eliminate duplicate vias.
• Perform batch design rule checking (DRC).
• Upgrade databases more than one revision old.

To verify the integrity of a drawing database at any time during the design cycle, run DBDoctor at regular intervals but make sure you always run it after completing a design.

You can run DBDoctor to verify work in progress, or from a terminal window outside the layout editor, perhaps to check multiple input designs in batch mode by using wildcards and various switches. You do not have to run the layout editor to use DBDoctor.

To run this from Allegro X APD and Allegro PCB Editor, go to Tools > Database Check.

You can also go to the Start menu and select Cadence PCB Utilities 2023 > PCB DB Doctor 2023.

You can also use the following command to run DBDoctor in batch mode in the system command prompt:

dbdoctor [-check_only] [-drc] [-drc_only] [-shapes][-no_backup] [-outfile <newboardname.brd>]>

Comment below if you want to know more about this command and its integration with SKILL programming!!

Hey, is it suitable to post here? I wanted a small yet robust amp for practicing while I travel. I wanted something that would fit in my pocket yet still be loud enough to hear.

Presented here is a amplifier based upon the LM386 Audio Amplifier.

There is a standard circuit in the data sheet that is an excellent place to start.

Materials needed:
1 - HM359 project box
1 - 668-1237 speaker
1 - BS6I battery conn
1 - CP1-3515 stereo jack
1 - SC1316 stereo jack
2 - 450-1742 knob
1 - 679-1856 switch
1- 3mm LED
1 - 10 ohm 1/4W resistor
1 - 10uF ceramic cap
1 - .05 uF ceramic cap
1 - 420 uF electrolytic cap
1 - 8 ohm resistor
2 - 51AADB24 10K pot
1 - HM1252 circuit board
1 - LM386N-4 amplifier

Wire and Solder
Step 1: Prep the enclosure

Careful planning is required the first time you free build a circuit. The circuit board has solder pads but not traces. You will have to use thin wire to make the connections for the circuit to work.

Begin by laying out the components on the circuit board that will need to pass through the enclosure. This enclosure has a removable top panel which will be used for the volume, gain and 1/4 inch stereo jack.

Space is limited to check for fit before drilling.

All drilling of the plastic should be done with a step drill bit. This will make the cleanest holes without breaking the plastic.

Lay out the pots a few spaces back but still in line with the desired position. mark the center of each pot shaft then drill with a step drill tot he tightest fitting hole size. Make a center mark between the pot holes then drill for the stereo jack

On the inside of the top cover position and mark where the speaker will go.

Make a template on grid paper the same size as the speaker.

Tape the template to the inside of the cover as shown then use a step bit to drill holes on the center of every square in the grid. This will form the speaker grille. clean up the holes.

Step 2: place the major components

Solder the pots to the circuit board as shown. then place the stereo jack(note in order to get the final fit I had to trim and modify the stereo jack housing a little)

Next, position and solder the switch on the circuit board and mark a space on the top cover that will need to be cut for the switch opening. Use a small file to cut the opening.

Use a sharp knife to bevel the edges of the switch hole to allow for easier operation.

Drill a hole in the side of the upper case for the headphone jack and fasten it in place. ( I had to recess the hole a bit for the retaining nut to grab)

Step 3: Build the circuit

The speaker is held in place by using 2 small brackets that come with the serial cable connector hood. ( I had a bunch around that would never be used)

Refer the the circuit shown from the datasheet and the datasheet for the LM386. The basic circuit only has the volume control while the datasheet shows how to add a gain control across pins 1 and 8 of the amplifier.

The speaker is wired in series with the headphone jack. The headphone jack has internal switches that shut the speaker off when the phones are plugged in.

I chose to use a chip socket for the amplifier which make prototyping easier since you do not have to worry about solder heating as much.

Carefully lay the circuit out on the board and begin wiring components together. I added a second pot and cap in series between pins 1 and 8 of the amp to be able to manually set the gain in addition to volume.

Check you connections with a multimeter before adding the amplifier.

I chose to add a LED indicator for power. This was done by using one side of switch contacts from the battery. The LED is in series with a 220 ohm resistor.

Assemble the case and insert the battery.

Step 4: Final notes

If the speaker is noisy while the headphones work normally, try reversing the speaker connections. If it does not correct the issue, connect a 8 ohm resistor across the speaker contacts.

You may have to place an insulating layer between the speaker and the place where the stereo jack comes through to prevent contact. This will be noted by a loud buzz.

You may have to add some foam in the battery compartment to stop the battery from banging around.

For reference, I've also read an article about amplifiers: http://www.apogeeweb.net/article/60.html

Thanks for reading!

This is the 15th installment of The Rationalist, my column for the Times of India.

It’s election season, and promises are raining down on voters like rose petals on naïve newlyweds. Earlier this week, the Congress party announced a minimum income guarantee for the poor. This Friday, the Modi government released a budget full of sops. As the days go by, the promises will get bolder, and you might feel important that so much attention is being given to you. Well, the joke is on you.

Every election, HL Mencken once said, is “an advance auction sale of stolen goods.” A bunch of competing mafias fight to rule over you for the next five years. You decide who wins, on the basis of who can bribe you better with your own money. This is an absurd situation, which I tried to express in a limerick I wrote for this page a couple of years ago:

POLITICS: A neta who loves currency notes/ Told me what his line of work denotes./ ‘It is kind of funny./ We steal people’s money/And use some of it to buy their votes.’

We’re the dupes here, and we pay far more to keep this circus going than this circus costs. It would be okay if the parties, once they came to power, provided good governance. But voters have given up on that, and now only want patronage and handouts. That leads to one of the biggest problems in Indian politics: We are stuck in an equilibrium where all good politics is bad economics, and vice versa.

For example, the minimum guarantee for the poor is good politics, because the optics are great. It’s basically Garibi Hatao: that slogan made Indira Gandhi a political juggernaut in the 1970s, at the same time that she unleashed a series of economic policies that kept millions of people in garibi for decades longer than they should have been.

This time, the Congress has released no details, and keeping it vague makes sense because I find it hard to see how it can make economic sense. Depending on how they define ‘poor’, how much income they offer and what the cost is, the plan will either be ineffective or unworkable.

The Modi government’s interim budget announced a handout for poor farmers that seemed rather pointless. Given our agricultural distress, offering a poor farmer 500 bucks a month seems almost like mockery.

Such condescending handouts solve nothing. The poor want jobs and opportunities. Those come with growth, which requires structural reforms. Structural reforms don’t sound sexy as election promises. Handouts do.

A classic example is farm loan waivers. We have reached a stage in our politics where every party has to promise them to assuage farmers, who are a strong vote bank everywhere. You can’t blame farmers for wanting them – they are a necessary anaesthetic. But no government has yet made a serious attempt at tackling the root causes of our agricultural crisis.

Why is it that Good Politics in India is always Bad Economics? Let me put forth some possible reasons. One, voters tend to think in zero-sum ways, as if the pie is fixed, and the only way to bring people out of poverty is to redistribute. The truth is that trade is a positive-sum game, and nations can only be lifted out of poverty when the whole pie grows. But this is unintuitive.

Two, Indian politics revolves around identity and patronage. The spoils of power are limited – that is indeed a zero-sum game – so you’re likely to vote for whoever can look after the interests of your in-group rather than care about the economy as a whole.

Three, voters tend to stay uninformed for good reasons, because of what Public Choice economists call Rational Ignorance. A single vote is unlikely to make a difference in an election, so why put in the effort to understand the nuances of economics and governance? Just ask, what is in it for me, and go with whatever seems to be the best answer.

Four, Politicians have a short-term horizon, geared towards winning the next election. A good policy that may take years to play out is unattractive. A policy that will win them votes in the short term is preferable.

Sadly, no Indian party has shown a willingness to aim for the long term. The Congress has produced new Gandhis, but not new ideas. And while the BJP did make some solid promises in 2014, they did not walk that talk, and have proved to be, as Arun Shourie once called them, UPA + Cow. Even the Congress is adopting the cow, in fact, so maybe the BJP will add Temple to that mix?

Benjamin Franklin once said, “Democracy is two wolves and a lamb voting on what to have for lunch.” This election season, my friends, the people of India are on the menu. You have been deveined and deboned, marinated with rhetoric, seasoned with narrative – now enter the oven and vote.

I need to add a new CDF parameter called "mag" to symbols in a given library using skill script in which the symbol size can be controlled and call back it each time this library is used so that all the symbols are updated.

First time user of JasperGold. Chip level verif. I want to prove that an arbiter and a buffer are connected. I want to use the connectivity app to do that.

I see from the user guide, that I should provide a connectivity map, but i have no idea how to construct one.
The training videos said use this command: check_conn -generate_template jasper_template.xlsm -xlsm
But that did nothing, or at least it did not produce a file that i could find

[<embedded>] % check_conn -generate_template jasper_template.xlsm -xlsm
ERROR (ESW104): Invalid command formation.
Problem occurs with "-generate_template -xlsm".

And even if it did, I don't even know what's in the file, and whether it contains the two ips I'm trying to check.

I'm hoping someone can give me a bit of a boost here with some knowledge.

Dear all,

Hi!

I'm trying to do a Harmonic Balance (HB) Large-Signal S-Parameter (LSSP) simulation to figure out the input impedance of a nonlinear circuit.

Through this simulation, what I want to know is the large-signal S11 only (not S12, S21 and S22).

So, I have simulated with only single port (PORT0) at input, but LSSP simulation is terminated and output log shows following text.

" Analysis `hb' was terminated prematurely due to an error "

The LSSP simulation does not proceed without second port.

Should I use floating second port (which is not necessary for my circuit) to succeed the LSSP simulation?

Does the LSSP simulation really need two ports?

Below figure is my HB LSSP simulation setup.

Additionally, Periodic S-Parameter (PSP) simulation using HB is succeeded with only single port.

What is the difference between PSP and LSSP simulations?
