anyone know what is "cell with Zero maximum clock transition time"  ?

not zero transition, not maximum transtion, it is zero maximum clock transition time.

it means X0 cell? (drive-strength)

can you explain? 

thanks :-)

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.

Why Is DSC Needed?

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 Key Features

• Encoding tools:
  • Modified Median-Adaptive Prediction (MMAP)
  • Block Prediction (BP)
  • Midpoint Prediction (MPP)
  • Indexed color history (ICH)
  • Entropy coding using delta size unit-variable length coding (DSU-VLC)

• The DSC bitstream and decoding process are designed to facilitate the decoding of 3 pixels/clock in practical hardware decoder implementations. Hardware encoder implementations are possible at 1 pixel/clock.
• DSC uses an intra-frame, line-based coding algorithm, which results in very low latency for encoding and decoding.

DSC encoding algorithm
 

• Compression can be done to a fractional bpp. The compressed bits per pixel ranges from 6 to 63.9375.
• For validation/compliance certification of DSC compression and decompression engines, cyclic redundancy checks (CRCs) are used to verify the correctness of the bitstream and the reconstructed image.
• DSC supports more color bit depths, including 8, 10, 12, 14, and 16 bpc.
• DSC supports RGB and YCbCr input format, supporting 4:4:4, 4:2:2, and 4:2:0 sampling.
• Maximum decompressor-supported bits/pixel values are as listed in the Maximum Allowed Bit Rate column in the table below

• DP DSC Source device shall program the bit rate within the range of Minimum Allowed Bit Rate column in the table:

Summary

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.

Hi

In the environment I'm currently working, axes are shown for schematic, symbol, and layout views.For schematics and symbols, I'd prefer a dim gray, such that the axes are just visible but not dominant. For the layout, I'd prefer a brighter color. Is there a way to realize this? So far when I change the color of the 'axis' layer in the display resource editor, the axes in all three views get changed together:

Hello

i did a sp-Analysis and now i want to extract the maximum value of the s11 trace and the corresponding frequency.

I already tried ymax() in the calculator but i am suspecting it only works on transient Signals.

Hello,

I have been running this `uvm_reg_hw_reset_seq` sequence for the AHB protocol. My UVM Adapter looks like:

Issue: When I use basic reg.write, my write access are working well, as that is managed by the driver i.e. once adapter gives the packet to the driver, the driver supplies the address and the control signals to the DUT on the first clock cycle and then the write data on the next clock cycle. But when I am performing the read operation, somehow the UVM adapter is reading the data at the same clock cycle where read address + Controls are supplied and this is triggering read failure messages from the `uvm_reg_hw_reset_seq` sequence. What should I modify in the driver/sequencer/adapter so that the UVM adapter can read the data on the next cycle instead of the same clock cycle.

Just FYI: The waveforms of the read operation are correct, it is just the Adapter and the `uvm_reg_hw_reset_seq`. The AHB Driver + AHB Monitor is fully proven and verified to be working correctly.

Glioblastoma (GBM) is a disease of the whole brain, with infiltrative tumor cells protected by an intact blood-brain barrier (BBB). GBM has a poor prognosis despite aggressive treatment, in part due to the lack of adequate drug permeability at the BBB. Standard of care GBM therapies include radiation and cytotoxic chemotherapy that lead to DNA damage. Subsequent activation of DNA damage response (DDR) pathways can induce resistance. Various DDR inhibitors, targeting the key regulators of these pathways such as ataxia telangiectasia mutated and Rad3-related (ATR), are being explored as radio- and chemosensitizers. Elimusertib, a novel ATR kinase inhibitor, can prevent repair of damaged DNA, increasing efficacy of DNA-damaging cytotoxic therapies. Robust synergy was observed in vitro when elimusertib was combined with the DNA-damaging agent temozolomide; however, we did not observe improvement with this combination in in vivo efficacy studies in GBM orthotopic tumor-bearing mice. This in vitro–in vivo disconnect was explored to understand factors influencing central nervous system (CNS) distribution of elimusertib and reasons for lack of efficacy. We observed that elimusertib is rapidly cleared from systemic circulation in mice and would not maintain adequate exposure in the CNS for efficacious combination therapy with temozolomide. CNS distribution of elimusertib is partially limited by P-glycoprotein efflux at the BBB, and high binding to CNS tissues leads to low levels of pharmacologically active (unbound) drug in the brain. Acknowledging the potential for interspecies differences in pharmacokinetics, these data suggest that clinical translation of elimusertib in combination with temozolomide for treatment of GBM may be limited.

Inositol 1,4,5-triphosphate receptor type 1 (ITPR1) is an endoplasmic reticulum–bound intracellular inositol triphosphate receptor involved in the regulation of intracellular calcium. Pathogenic variants in ITPR1 are associated with spinocerebellar ataxia (SCA) types 15/16 and 29 and have recently been implicated in a facial microsomia syndrome. In this report, we present a family with three affected individuals found to have a heterozygous missense c.800C > T (predicted p.Thr267Met) who present clinically with a SCA29-like syndrome. All three individuals presented with varying degrees of ataxia, developmental delay, and apparent intellectual disability, as well as craniofacial involvement—an uncommon finding in patients with SCA29. The variant was identified using clinical exome sequencing and validated with Sanger sequencing. It is presumed to be inherited via parental germline mosaicism. We present our findings to provide additional evidence for germline mosaic inheritance of SCA29, as well as to expand the clinical phenotype of the syndrome.

TOKYO — U.S. and Japanese diplomats agreed Tuesday to maximize pressure on North Korea to resolve tensions over its nuclear program, while citing the need to be prepared for the worst if diplomacy fails.

U.S. Deputy Secretary of State John Sullivan, after meeting his Japanese counterpart, Shinsuke Sugiyama, told reporters that the focus at the State Department is still on diplomacy to solve the problem and eventually denuclearize the Korean Peninsula.

“We must, however, with our allies in Japan and South Korea and elsewhere, be prepared for the worst should diplomacy fail,” he said. The U.S. must be prepared to defend itself and its allies, he said.

Sugiyama, briefing reporters separately, reiterated Japan’s support for President Donald Trump’s policy of keeping all options open, but stressed the need for a diplomatic solution by bolstering cooperation among Japan, U.S. and South Korea, as well as via cooperation with China and Russia.

The two diplomats will join their South Korean counterpart in Seoul for further talks Wednesday on North Korea.

The talks come as the U.S. and South Korea hold joint naval drills this week. They regularly conduct joint exercises, though North Korea condemns them as an invasion rehearsal.

North Korea’s deputy U.N. ambassador warned on Monday that the situation on the peninsula “has reached the touch-and-go point and a nuclear war may break out any moment.”

Kim In Ryong told the U.N. General Assembly’s disarmament committee that North Korea has been subjected to a direct nuclear threat from the United States and has the right to possess nuclear weapons in self-defense.

He pointed to military exercises and what he called a U.S. plan to stage a “secret operation aimed at the removal of our supreme leadership.”

Kim’s speech follows increasingly tough U.N. sanctions. Russian President Vladimir Putin said his country is curtailing economic, scientific and other ties with North Korea in line with U.N. sanctions, and the European Union announced new sanctions as well.

We’re reprinting the Seventy Maxims “defaced” edition, and the crowdfunding project for that wraps up in just under a week.

As part of this project I’m designing two posters, both of which will have all seventy maxims on them. Yesterday I spent a few hours tweaking various text attributes like kerning and quote height, and finished up the two-column version of the poster. It’ll be a 16″x20″ thing, and will look something like this…

If you want to get your hands on one of these posters, perhaps for the wall of your office, or maybe the local kindergarten, jump in on the Backerkit project today. We’ll be printing extras, of course, but backing the project is the only way to ensure that we set one aside for you.

And speaking of Backerkit… this project is an experiment, a stress-test of a new soup-to-nuts crowdfunding service, an alternative to Kickstarter. For several projects we’ve used Backerkit in conjunction with Kickstarter, because Backerkit makes fulfilment easier for complex projects. They’ve been around for a while, and we love working with them.

We still like working with Kickstarter, but it’s good to have an alternative—especially since Kickstarter briefly flirted with adding NFTs to their blockchain infrastructure, sending much of their community scrambling for other options. They’ve backed away from that ledge, at least for now, which makes us happy. Also, we are happy to be trying out a different service. We like having options.

Unsurprisingly, there are a couple of maxims that may apply here:

50: If it only works in exactly the way the manufacturer intended, it is defective.
30: A little trust goes a long way. The less you use, the further you’ll go.

(You, too, can cite maxims as if from memory… all you need is one of these fancy new posters on a wall where you can see it.)

Today’s the final day of (the final hours, at this point) of the Seventy Maxims Reprint project. Here, then is a nice origin story for you, the origin of Maxim 32.

I was signing and sketching at GenCon Indy a decade or so ago when some young men approached the table. They were what a friend of mine likes to call “baby sailors”: relatively new members of the US Navy. One of them said “we have a suggestion for a maxim.”

I smiled. “Let’s hear it.”

“Anything is amphibious if you can fit it into an AAV.”

I chuckled. “That’s pretty good, but the term ‘AAV’ is too specific for Schlock Mercenary use.” Then I went silent, stared off into the distance, and I guess this made everyone uncomfortable because our Booth Captain, Darren, spoke next.

“Shhh… don’t interrupt him. The magic is happening.”

It’s true, I’d been wondering how this US Navy aphorism could be repurposed, but I had expected to be able to mull it over all day. Now, however, Darren had turned it into the promise of performance art. Did I curse silently? Maybe. I don’t remember, because I was panicking.

Still staring into space, trying not to show fear, I dove into the “formulae” for the maxims. I knew that many of the maxims were subversions of existing aphorisms. Several of them formed thematic couplets, like Maxims 2 and 3 (“a sergeant in motion” and “an ordnance tech in motion”) are a great example of this. And Maxim 23, “Anything is air-droppable at least once,” seemed like a good candidate for pairing with what the Navy boys had suggested, especially since “Anything is air-droppable” and “Anything is amphibious” were already pretty close.

All I needed to do was break the amphibious-ness in the same way I’d broken the air-droppability… and I think it was that moment, when I contemplated “breaking” amphibious-ness, when the final text arrived in my head.

“Anything is amphibious if you can get it back out of the water.”

A quick note. The United States Navy exists to keep things DRY. Everything except the hulls, really. The very idea of dropping something into the water that is not already a boat, runs counter to Navy thinking.

So it’s no surprise that those Navy boys were visibly horrified by my subversion of their aphorism. “That’s terrible” one of them said. And then they started to laugh.

And then I wrote Maxim 32 in my notebook, because obviously it was perfect.
