In Delhi, the comparison made from the second week of March (before lockdown) to first week of April (April 6), reduction in PM2.5 was found to be by 62 per cent, PM10 by 57 per cent and NOx by 50 per cent,  the latest SAFAR data accessed by PTI showed.

Weeks of lockdown in the country to fight coronavirus may have reduced greenhouse gas emissions enabling people to breathe cleaner air and feast on blue skies, but it is only a temporary phase and will not benefit the environment in the long run.

In its report, the CPCB said, "Significant reduction in PM2.5, PM10 and NO2 levels observed. Overall, 46 per cent reduction in PM2.5 and 50 per cent reduction in PM10 concentration observed during the lockdown period."

Smart Lock Company LockState raised $5.8M Series A in new investment to fund its aggressive sales and marketing and partner development plan. The company previously raised $740K seed round and $1M in a round led by angel investors. The lead investor in latest round was Iron Gate Capital. Other investors include Kozo Keikaku Engineering Inc, Nelnet and Service Provider Capital.

The company’s Wi-Fi-enabled RemoteLock is used by 1000s of Airbnb and other vacation rental hosts. It helps hosts remotely provide access to guests. Locking/unlocking codes can be generated via a host’s computer or smartphone.

RemoteLock’s prices start at $299 which is its algorithmic ResortLock. The most pricey lock by LockState is its ‘RemoteLock 7i Black WiFi Commercial Smart Lock’ which costs $479.

Another core product of LockState is its cloud-based remote access platform for internet-enabled locks. It implies users can remotely manage their (internet-enabled) locks via LockState’s cloud platform.

Unlike smartphones and watches, customers don’t look forward to upgrading their smart locks or buying one when new models are launched. Thus, smart lock companies offset this disadvantage by partnering with property management and short-term rental companies to get new customers.

LockState has partnered with vacation rental brands like Airbnb, HomeAway, and other listing partners to automate guest access.

Reported cases of domestic violence in Russia have more than doubled during the country’s coronavirus lockdown, according to the Russian human rights commissioner, who painted a different picture to that provided by police data.

Complaints and reports made to Russian non-governmental organisations spiked from roughly 6,000 in March to more than 13,000 in April, Tatyana Moskalkova said on Tuesday. “The picture is rather non-optimistic,” the RIA Novosti news agency quoted her as saying.

I have completed physical design of a block in innovus. I want to extract rc of that block using quantus .  It will be very helpful if you give step by step procedure and command to run quantus to extract rc of that block.

When I enable clock gating in my synthesis flow (using Genus 18.15), my simulation (using Xcelium) on the post-synthesis netlist fails. The simulation succeeds pre-synthesis and also if I remove clock-gating in the design. I use set_db  lp_insert_clock_gating true to enable clock gating during synthesis. I printed out some of the signals from the netlist and can see where it fails (it incorrectly writes a register). However, I am not sure how to solve this issue or what I should be looking for. Any help would be appreciated. Thanks.

Hello,

Would anyone know how to setup a PSS or QPSS simulation with 25% dutycycle clock sources or if such a thing is possible with QPSS.

Fig1 (below) is a snapshot of the circuit I am trying to characterize. This has 4 clock ports each with 25%duty cycle in the ON state. Fig2 below shows two of these clocks.

Each path in the circuit consists of two switches with a low pass RC sandwiched in between. The Input is a 50Ohm port sine wave and the output is a 1K resistor. The output nets of all paths are connected together.

I am trying to determine the swept frequency response from input to output (voltage) when the input is from 500Mhz to  510MHz. The Period (T=1/Fp) of each of the pulses is such that Fp=500MHz. The first pulse source has a delay=0, second has delay=T/4, third delay=2T/4, etc...

I am currently getting it working and seeing the correct result (bandpass response) with Transient but the problem is doing a dft at 500MHz with 10KHz spacings needs at least 100us and takes up a lot of time and disk space.

Many Thanks,
Chris.

I am trying to understand why axlDBTextBlockCompact(nil) on my test case says it can compact the text blocks down to 38, whereas I find only a total of 26 unique text block references in axlDBGetDesign()->text, axlDBGetDesign()->symbols and axlDBGetDesign()->symdefs. Where else are text blocks used besides these three?

Hi,

I wanted to find the location of a pin in the design using skill program. pin_dbids = axlDBGetDesign()->pins, this gives me all the dbids of the pins that are present in my design. But when im entering that dbid, pad = axlDBGetPad("000001EA8FD8B9F8" "package geometry/assembly_top" "regular") it is throwing an error stating "This dbid is not user defined. Please enter the user defined". So please provide me a snippet so that I can get the exact pin location in the design using skill script.

Hi

Hi everybody,

I've created a symbol with custom pad shapes. Everything looks correct in the symbol editor.

And the 3d view looks correct (upside down to show placement)

But when I try to place it on the pcb the 2 "T" shaped pads aren't in the correct location.

I have the pad shape centered on the pad...

with no offset on the padstack editor.

Does anybody know how to fix this?

Thank you!

Hi,

I am currently struggling with measuring the delay between two clocks with a sufficient accuracy. The reference one is a fixed-phase clock, and the other one is a squared clock resulting of a circuit (kind of PLL) synthesis.
As I need to run a large amount of Monte-Carlo simulations in transient noise, I need to improve the simulation speed, while keeping a satisfactory delay measurement accuracy (<0.1ps), more specifically at 0V-crossings of the differential clocks. So I cannot simply set a max timestep <0.1ps as it would be far too long to simulate.
To sum up, I would need a very relaxed timestep on clock up and down levels, and a very short timestep only at rise/fall transitions.

For this purpose, I wrote a Verilog-A script
- using a timmer function to accurately emulate the reference clock 0V-crossing times (and get the related times with $abstime)
- using @(cross to get the 0V-crossing times of the synthesized clock: but this is not accurate enough (I see simulation noise around 3ps in Conservative). Indeed, the "cross" event occures at the simulation time following the effective 0V-crossing time; this could be sometimes >3ps, far not enough accurate for my purpose.
- I have tried to replace the cross with the "above" function, but it hasn't changed anything, whatever the time_tol value I put (<0.1ps for instance), the result is the same as with the "cross" function and the points are larger than >>0.1ps, weirdly.

So I have decided to give up Verilog-A to measure the delay between my two clocks.
I am currently trying to use the "delay" function of the Cadence Calculator as I guess it will "extrapolate" the time between two simulation points and therefore give a more accurate measurement of the 0V-crossing events, but when I try to compute the delay difference between the synthesized clock and the reference clock, it returns "0".

...

Could you please give me hints to dramatically improve my 0V-crossing time measurements while relaxing the simulation time?
- either by helping me in writing a more suitable Verilog-A script
- or by helping me in using the "delay" function of the calculator
- or maybe by providing me a "magic" Skill function?
Using AMS+Multithread simulator...

Thanks a lot in advance for your help and best regards.
