Scientists have spotted microplastics, tiny pieces of plastic smaller than 5 millimeters, in some of the most pristine environments on Earth, from the depths of the Mariana Trench to the snow on Mt. Everest to the mountaintop clouds of China and Japan. Microplastics have been detected in human brains, the bellies of sea turtles and the roots of plants. Now, new research led by Penn State scientists reveals that microplastics in the atmosphere could be affecting weather and climate.

A study published in iScience found that chimpanzees performed better on challenging tasks when observed by humans. The research, conducted by Kyoto University, revealed that the presence of a larger human audience improved performance on difficult tasks, while simpler tasks saw a decline in accuracy. This suggests that the audience effect, often linked to human reputation management, may also exist in non-human primates. The study provides insights into social behaviours that might have evolved before the emergence of human reputation-based societies.
The lower-end Xbox Series S has run into hardware bottlenecks in the past when it comes to new releases, and concerns have been raised about whether the console would be able to run GTA 6 without problems.

We are looking for suitable tools that could be used for RTL design, IP-XACT based integration (third party IP) and RTL design verification ( SV / UVM based methodology).
Request to share details on the different Cadence tools that is most suitable for these activities.
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!

WHEN I COMPARING MY GOLDEN.V WITH HDL_min_Netlist.v during conformal , I got these non-equivalent point for every reg memory and for every data memory. I don't know what to do with these non-equivalent point. I've been stuck here for the past four days. Please help me in this and how can I remove this non- equivalent point , since I am new to this I really don't know what to do.
hi
How can I tell the LEC tool to ignore a combination of Primary input bus in both Golden and revised.
For example in both Golden and revised there is
input [3:0] data_in
I want LEC not to check the case that data_in[3:0] == 4'b1000
Xcelium Simulator has been in the industry for years and is the leading high-performance simulation platform. As designs are getting more and more complex and verification is taking longer than ever, the need of the hour is plug-and-play apps that ar...(read more)
Speed increase requirements keep on flowing by in all the domains surrounding us. The same applies to memory storage too. Earlier mobile devices used eMMC based flash storage, which was a significantly slower technology. With increased SoC processing speed, pairing it with slow eMMC storage was becoming a bottleneck. That is when modern storage technology Universal Flash Storage (UFS) started to gain popularity.
UFS is a simple and high-performance mass storage device with a serial interface. It is primarily used in mobile systems between host processing and mass storage memory devices. Another important reason for the usage of UFS in mobile systems like smartphones and tablets is minimum power consumption.
To achieve the highest performance and most power-efficient data transport, JEDEC UFS works in collaboration with industry-leading specifications from the MIPI® Alliance to form its Interconnect Layer. MIPI UniPro is used as a transport layer, and MIPI MPHY is used as a physical layer with the serial DpDn interface.
UFS 4.0 specification is the latest specification from JEDEC, which leverages UniPro 2.0 and MPHY 5.0 specification standards to achieve the following major improvements:
Along with many major enhancements, UFS 4.0 also maintains backward compatibility with UFS 3.0 and UFS 3.1.
JEDEC has just announced the UFS 4.0 specification release, quoting Cadence support as a constant contributor in the JEDEC UFS Task Group, actively participating in these specifications development.
With the availability of the Cadence Verification IP for JEDEC UFS 4.0, MIPI MPHY 5.0 and MIPI UniPro 2.0, early adopters can start working with the provisional specification immediately, ensuring compliance with the standard and achieving the fastest path to IP and SoC verification closure.

Display Stream Compression (DSC) is a lossless or near-lossless image compression standard developed by the Video Electronics Standards Association (VESA) for reducing the bandwidth required to transmit high-resolution video and images. DSC compresses video streams in real-time, allowing for higher resolutions, refresh rates, and color depths while minimizing the data load on transmission interfaces such as DisplayPort, HDMI, and embedded display interfaces.
In the ever-evolving landscape of display technology, the pursuit of higher resolutions and better visual quality is relentless. As display capabilities advance, so do the challenges of managing the immense amounts of data required to drive these high-performance screens. This is where DSC steps in. DSC is designed to address the challenges of transmitting ultra-high-definition content without sacrificing quality or performance. As displays grow in resolution and capability, the amount of data they need to transmit increases exponentially. DSC addresses these issues by compressing video streams in real-time, significantly reducing the bandwidth needed while preserving image quality.
DSC Use in End-to-end System
DSC encoding algorithm
Display Stream Compression (DSC) is a technology used in DisplayPort to enable higher resolutions and refresh rates while maintaining high image quality. It works by compressing the video data transmitted from the source to the display, effectively reducing the bandwidth required. DSC uses a visually lossless algorithm, meaning that the compression is designed to be imperceptible to the human eye, preserving the fidelity of the image. This technology allows for smoother, more detailed visuals at higher resolutions, such as 4K or 8K, without requiring a significant increase in data bandwidth.

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!
Hi, I'm using the xcelium simulator to simulate a testbench, in which I first stimulate my design to do something (part "A") and then do a direct follow-up test on the design (part "B").
I need two things from this testbench: the results of the test (part "B", passed/failed) and coverage information, but the coverage information should only include part A and explicitly not part B.
I could do the following: run the testbench with part A and B, get the "passed/failed" result of the test and then follow up another simulator run with another testbench, that only includes part A and get the coverage information from that simulation run.
Is there a way to force xcelium to give me the coverage information of only a part of the simulation? Ideally, I would like to write the verilog code of my testbench to look something like this:
But maybe there is another way to tell xcelium to consider only part of the testbench for the coverage information. I did have a look at the manual, but was not able to find something useful for this problem. Any ideas?
