Delaware has been experiencing a significant increase in potbellied pigs running at large in residential and rural areas, including on state lands. Running at large, these pigs pose a nuisance to landowners, increase the threat of establishing feral pig populations, damage natural resources, and risk carrying endemic diseases that can spread to both people and animals.

On June 1, a new regulation was published in the Delaware Register of Regulations (Volume 26, Issue 12) listing potbellied pigs and feral swine of any kind as invasive. The Delaware Department of Agriculture (DDA) is providing a 30-day grace period for potbellied pig owners to apply for an Invasive Animal Permit. Owners have until August 12 to submit an application and comply with 3 DE Admin. Code 906 Possession, Sale, or Exhibition of Non-Native and Invasive Animal Species.

Hi Cadence & forumers, 

I am running a conformal LEC with a flattened netlist against RTL. 

The run hang for 5 days at the "analyze abort" step which is automatically launched by the compare. 

The netlist is flattened at some levels so hierarchical flow which I tried didn't help much. The flattened/highly optimized netlist is from customer and the ultimate goal. How shall I proceed now? 

On the a side note, a test run with a hierarchical netlist from a simple DC "compile -map_effort medium" command finished after 1 day or so. 

Thank you!

Melika Roshandell, Cadence product marketing director for the Celsius Thermal Solver, recently published an article in Designing Electronics discussing how the use of modern thermal analysis techniques can help engineers meet the challenges of today’s complex electronic designs, which require ever more functionality and performance to meet consumer demand.

Today’s modern electronic designs require ever more functionality and performance to meet consumer demand. These requirements make scaling traditional, flat, 2D-ICs very challenging. With the recent introduction of 3D-ICs into the electronic design industry, IC vendors need to optimize the performance and cost of their devices while also taking advantage of the ability to combine heterogeneous technologies and nodes into a single package. While this greatly advances IC technology, 3D-IC design brings about its own unique challenges and complexities, a major one of which is thermal management.

To overcome thermal management issues, a thermal solution that can handle the complexity of the entire design efficiently and without any simplification is necessary. However, because of the nature of 3D-ICs, the typical point tool approach that dissects the design space into subsections cannot adequately address this need. This approach also creates a longer turnaround time, which can impact critical decision-making to optimize design performance. A more effective solution is to utilize a solver that not only can import the entire package, PCB, and chiplets but also offers high performance to run the entire analysis in a timely manner.

Celsius Thermal Management Solutions

Cadence offers the Celsius Thermal Solver, a unique technology integrated with both IC and package design tools such as the Cadence Innovus Implementation System, Allegro PCB Designer, and Voltus IC Power Integrity Solution. The Celsius Thermal Solver is the first complete electrothermal co-simulation solution for the full hierarchy of electronic systems from ICs to physical enclosures. Based on a production-proven, massively parallel architecture, the Celsius Thermal Solver also provides end-to-end capabilities for both in-design and signoff methodologies and delivers up to 10X faster performance than legacy solutions without sacrificing accuracy.

By combining finite element analysis (FEA) for solid structures with computational fluid dynamics (CFD) for fluids (both liquid and gas, as well as airflow), designers can perform complete system analysis in a single tool. For PCB and IC packaging, engineering teams can combine electrical and thermal analysis and simulate the flow of both current and heat for a more accurate system-level thermal simulation than can be achieved using legacy tools. In addition, both static (steady-state) and dynamic (transient) electrical-thermal co-simulations can be performed based on the actual flow of electrical power in advanced 3D structures, providing visibility into real-world system behavior.

Designers are already co-simulating the Celsius Thermal Solver with Celsius EC Solver (formerly Future Facilities’ 6SigmaET electronics thermal simulation software), which provides state-of-the-art intelligence, automation, and accuracy. The combined workflow that ties Celsius FEA thermal analysis with Celsius EC Solver CFD results in even higher-accuracy models of electronics equipment, allowing engineers to test their designs through thermal simulations and mitigate thermal design risks.

Conclusion

As systems become more densely populated with heat-dissipating electronics, the operating temperatures of those devices impact reliability (device lifetime) and performance. Thermal analysis gives designers an understanding of device operating temperatures related to power dissipation, and that temperature information can be introduced into an electrothermal model to predict the impact on device performance. The robust capabilities in modern thermal management software enable new system analyses and design insights. This empowers electrical design teams to detect and mitigate thermal issues early in the design process—reducing electronic system development iterations and costs and shortening time to market.

Hello,

I am new in formal verification and I have a concept question about how to verify an I2C Slave block.

I think the response should be valid for any serial interface which needs to receive information for several clocks before making an action.

The the protocol description is the following: 

I have a serial clock (SCL), Serial Data Input (SDI) and Serial Data Output (SDO), all are ports of the I2C Slave block.

The protocol looks like this:

The first byte which is received by the slave consists in 7bits of sensor address and the 8th bit is the command 0/1 Write/Read.

After the first 8 bits, the slave sends an ACK (SDO = 1 for 1 clock) if the sensor address is correct.

Lets consider only this case, where I want to verify that the slave responds with an ACK if the sensor address is correct.

The only solution I found so far was to use the internal buffer from the block which saves the received bits during 8 clocks. The signal is called shift_s.

I also needed to use internal chip state (state_s) and an internal counter (shift_count_s).

Instead of doing an direct check of the SDO(sdo_o) depending on SDI (sdi_d_i), I used the internal shift_s register.

My question is if my approach is the correct one or there is a possibility to write the verification at a blackbox level.

Below you have the 2 properties: first checks connection from SDI to internal buffer, the second checks the connection between internal buffer and output.

property prop_i2c_sdi_store;
  @(posedge sclk_n_i)
  $past(i2c_bl.state_s == `STATE_RECEIVE_I2C_ADDR)
    |-> i2c_bl.shift_s == byte'({ $past(i2c_bl.shift_s), $past(sdi_d_i)});
endproperty
APF_I2C_CHECK_SDI_STORE: assert property(prop_i2c_sdi_store);

property prop_i2c_sensor_addr(sens_addr_sel, sens_addr);
@(posedge sclk_n_i) (i2c_bl.state_s == `STATE_RECEIVE_I2C_ADDR) && (i2c_addr_i == sens_addr_sel) && (i2c_bl.shift_count_s == 7)
  ##1 (i2c_bl.shift_s inside {sens_addr, sens_addr+1}) |-> sdo_o;
endproperty
APF_I2C_CHECK_SENSOR_ADDR0: assert property(prop_i2c_sensor_addr(0, `I2C_SENSOR_ADDRESS_A0));
APF_I2C_CHECK_SENSOR_ADDR1: assert property(prop_i2c_sensor_addr(1, `I2C_SENSOR_ADDRESS_A1));
APF_I2C_CHECK_SENSOR_ADDR2: assert property(prop_i2c_sensor_addr(2, `I2C_SENSOR_ADDRESS_A2));
APF_I2C_CHECK_SENSOR_ADDR3: assert property(prop_i2c_sensor_addr(3, `I2C_SENSOR_ADDRESS_A3));

PS: i2c_addr_i is address selection for the slave (there are 4 configurable sensor addresses, but this is not important for the case).

Thank you!

Hello everyone. In recent days, I'm having a weird problem with sound output on my Windows 10 PC. In fact, I can't control the loudness of it. So is there any possibility of PCB of sound card being damaged?

Hello Everybody

Recently, I want to design a high output Power Amplifier at 2.4GHz using TSMC 1P6M CMOS Bulk Process. I use its nmos_rf_25_6t transistor model to determine the approximate mosfet size

I use the most common Common-Source Differential Amplifier topology with neutralizing capacitor to improve its stability and power gain performance

Because I want to output large power, the size of mosfet is very large, the gate width is about 2mm, when I perform harmonic balance analysis, everything is alright, the OP1dB is about 28dBm (0.63Watt)

But When I perform Transient simulation, the magnitude of voltage and current waveform at the saturation point is too small, for voltgae, Vpeaking is about 50mV, for current, Ipeaking is about 5mA

I assume some reasons: the bsim4 model is not complete/ the virtuoso version is wrong (My virtuoso version is IC6.1.7-64b.500.21)/the spectre version is wrong (spectre version is 15.1.0 32bit)/the MMSIM version is wrong/Transient Simulation setting is wrong (the algorithm is select gear2only, but when I select other, like: trap, the results have no difference), the maxstep I set 5ps, minstep I set 2ps to improve simulation speed, I think this step is much smaller than the fundamental period (1/2.4e9≈416ps)

I have no idea how to solve this problem, please help me! Thank you very very much!

Hi

I have tried using "add net constraints" command to place one-cold constraints on a tristate enable bus. In the command line we need to specify the "net pathname" on which the constraints are to be enforced.

The bus here is 20-bit. How should the net pathname be specified to make this 20-bit bus signals one_hot or one_cold.

The bus was declared as follows:
ten_bus [19:0]

The command I used was

add net constraints one_hot /ren_bus[19]

What would the above command mean?
Should we not specify all the nets' pathnames on the bus?
Is it sufficient to specify the pathname of one net on the bus?
I could not get much info regarding the functionality of this command. I would be obliged if anyone can throw some light.

Thanks
Prasad.

Optimizing PCB thermal performance is essential in today’s high-density designs, as it ensures stability, prolongs component life, and prevents potential thermal issues. One of the first steps to achieving this is with strategic component placement. Positioning high-power components—such as regulators, power transistors, or processors—away from heat-sensitive parts can prevent thermal interference, and placing them near the edges of the PCB often helps dissipate heat more effectively. It’s also beneficial to group components by their heat generation, creating dedicated thermal zones that can manage localized heating and reduce impact on other areas of the board.

Using thermal vias is another effective technique. By placing thermal vias under components like BGAs or power ICs, heat can be transferred from the surface to internal layers or ground planes. Increasing the size and number of these vias, or using thicker plating, enhances heat conductivity and helps manage heat more evenly across layers in multilayer boards. Increasing copper thickness on the PCB also has a major impact. Opting for thicker copper layers (e.g., 2 oz or even 3 oz copper) significantly boosts the heat dissipation capabilities of power planes and traces, especially in high-current areas. Large copper planes, such as dedicated ground or power planes, are equally effective in spreading heat efficiently. Adding thermal pads directly beneath heat-generating components improves this heat distribution.

Thermal relief pads help regulate heat flow for through-hole components by controlling heat transfer, which reduces thermal stress during soldering and prevents excessive heat spread to nearby sensitive areas. Performing thermal analysis with software tools like Celsius can be invaluable, as it allows you to simulate and model heat distribution, spot potential thermal issues, and refine your design before finalizing it.

Using heat sinks and thermal pads provides a direct way to draw heat from high-power components. Heat sinks can be attached with thermal adhesives, screws, or clamps, while thermal interface materials (TIMs), such as thermal pads or conductive adhesives, further reduce thermal resistance, enhancing heat-transfer efficiency. Optimizing the PCB layer stackup is also a key factor. Dedicated ground and power layers improve heat conduction across the PCB, enabling heat transfer between layers, particularly in high-density and multilayer PCBs.

In designs with high power requirements, active cooling options like fans, blowers, or heat pipes can be essential, helping to direct airflow across the PCB and further improving heat dissipation. Adding ventilation slots around hot zones and considering passive cooling paths enhance natural airflow, making the design more thermally efficient. By combining several of these techniques, you can create a PCB that handles heat effectively, resulting in a robust, long-lasting, and reliable product.

Let us know if you’ve had any challenges with thermal management in your designs—I’d be glad to discuss further!

Conformal ECO Designer enables you to implement RTL engineering change orders (ECOs) for pre- and post-mask layout and offers early ECO prototyping capabilities for driving critical project decisions.

Conformal ECO compares two designs and generates a functional patch that implements the changes between the two designs.

One major criterion for determining patch quality is whether the patch can meet timing closure. To determine this, you typically need to run the time-consuming process of incremental synthesis and place-and-route. Instead, Conformal can analyze path logic depth changes before and after ECO patch generation. This provides a faster way to evaluate timing impact in patch generation stages.

After the patch is created and applied, it is passed to Genus to optimize the patch.

During patch optimization, you can choose to do many things like:

• Keeping constants in the patch
• Allowing tie cell inversion
• Specifying tie cell types
• Preserve DFF cells and cell types in the patch
• Preserve all cells and nets in the patch
• Preserve clock buffer cell in the patch
• Turn on/off sequential constant and sequential merge in patch optimization
• Allowing phase mapping for DFFs
• Map to spare cells
• Force fix DRC before timing

What's Next?

• Use Conformal Engineering Change Order (ECO) for flat and hierarchical designs
• Generate a functional ECO patch, apply it to a design, optimize it, and map it to a specified technology
• Run a hierarchical design through ECO and run a comparison to prove the ECO is equivalent
• Run a postmask ECO using Conformal ECO GXL
