Hi,

My query is regarding importing of layout.

After importing, we see that the imported transistor instances and vias are all referring to the library in which they are imported, instead of referring to the technology library.

Please let me know how we can refer them to the technology library.

Will surely provide more details if my query is unclear.

Thanks,

Mallikarjun.

Hi,

I have synthesized a verilog code. When performing the pnr in innovus it is showing the error "Instance g5891__718 (similar for other) of the cell AND2_X6 has no physical library or has wrong dimension  values (<=0). Check your design setup to make sure the physical library is loaded in and attribute specified in library are correct.

When importing synthesized netlist in virtuoso then it says " Module AND2_X6, instantiated in the top module decoder, is not defined. Therefore the top module decoder will be imported as functional."

Please help what's going on here? 

At a bustling Cadence event, we met Adrian, an intern at a startup who immerses himself in Cadence tools for his research and work.

I'm not able to export a CIS Standard BOM to a Microsoft 365 Excel (business subscription, version 2111).
Selecting the "Export BOM report to Excel" option opens a new Excel window, but OrCAD (17.4-2019 S023) won't fill it with any data...

I tried it on a different PC with Microsoft Office Professional Plus 2019 Excel (strangely the version number is the same: 2111) and with OrCAD 17.4-2019 S016 and it worked flawlessly.

Does anybody experiencing the same issue?
Does the Excel variant, the OrCAD version or the PC itself causing this?
Thanks for any help!

I'm working on the code coverage. Doing a metrics analysis by default we see overall average grade and overall covered. But when i do a block analysis on an instance i see overall covered grade, code covered grade, block covered grade, statement covered grade, expression covered grade, toggle covered grade.

As I dont know the difference I started to read the IMC user guide and came to know there are 3 things we come across while doing a code coverage local, covered, average

From my understanding

local - child instances metrics doesnt reach the parent level. For example, we have an instance Q and its sub instances like Q.a, Q.b. Block Local grade of Q can be 100% even when its instances Q.a and Q.b a block local grades isnt at 100%.

In the attached image there is formula 

The key difference between average and covered is the weights.

Average : Mathematically taking the above scenario where Q.a, and Q.b has 10 blocks each. Q.a has covered 8 blocks and q.b has covered 2 blocks. Now if we take the normal average it should be total covered/ totatl number = 8+2/10+10 yielding 50%. But when we add weights saying Q.a is 70% and Q.b is 30% the new number would be (8*0.7+2*0.3) / (10*0.7+10*0.3) resulting 62%. Because of the weights we see 12% bump.

Covered: there is no role of weights.

Among these 3 metrics i've changed my default view to this in the image to get more realistic picture when i do analyze metrics. Do you guys agree with the approach?

Hi,
I want to parameterized width and length of a NMOS, but it ignore it and I face this error:
*WARNING* Value input must be a number - setting back to previous value.

Does anybody know how I can fix this issue?
Thanks

Power efficiency is a critical factor in the fast-evolving world of semiconductor design.

The IEEE 1801 standard, also known as UPF (Unified Power Format), was developed by the IEEE to address the intricate challenges associated with power management in contemporary semiconductor designs. This standard offers a uniform framework for defining power domains, power states, and power intent, ensuring consistency across diverse tools and phases of the design process. By utilizing UPF, you can precisely model and regulate power consumption, a critical aspect for battery-operated devices, high-performance computing, and energy-efficient designs.

The key concepts of IEEE 1801 are:

1. Power domains
2. Power states
3. Power gating and isolation
4. Power switches
5. Level shifters, isolation, and retention cells
6. Macro model

Based on these building blocks, you write the power intent of the design.

The power intent for the design includes identifying/implementing low-power strategies that provide a clear description of the power architecture of a design.

The power definitions can effectively manage power consumption and ensure the chip meets its power and performance requirements.

You can start by creating the Power Supply Network, which defines how power is supplied to the design's various power domains and logic cells.

What's the next step to build the file? How do you understand the various concepts related to IEEE 1801? How do you complete the rest of the power intent file?

Relax!

Tehran, Iran — A militant attack near the Pakistani border with Iran left five Iranian forces dead, the state-run IRNA news agency reported Sunday. The report said the dead were ethnic Baluch members of the paramilitary Revolutionary Guard's volunteer Basij force and were killed in Saravan city in Sistan and Baluchistan province. Saravan is some 1,400 km (870 miles) southeast of the capital Tehran. No group immediately claimed responsibility for the attack. Earlier in the day, state TV reported that Revolutionary Guard forces killed three terrorists and arrested nine others in a military operation. The report did not specify which group the suspects belonged to. Last month, unknown gunmen killed four people, including the chief of the Revolutionary Guard in the province. In September, gunmen killed four border guards in Sistan and Baluchistan province in two separate attacks. The militant group Jaish al-Adl, which seeks greater rights for the ethnic Baluch minority, claimed responsibility for one attack in which one officer and two soldiers were killed. The province, which borders Afghanistan and Pakistan, has been the site of occasional deadly clashes involving militant groups, armed drug smugglers and Iranian security forces. It is one of the least developed parts of Iran. Relations between the predominantly Sunni Muslim residents of the region and Iran's Shiite theocracy have long been strained.

ISLAMABAD — Pakistan said Saturday that four of its soldiers were killed when a "group of terrorists" from across the Iranian side of the border attacked a routine military patrol operating between the two countries.    The deadly cross-border raid took place in the remote Kech district in southwestern Baluchistan province abutting Iran, the Pakistani military said in a statement.  "Necessary contact with the Iranian side is being made for effective action against terrorists on the Iranian side and to prevent such incidents in the future," the statement said, without providing further details.      The Iranian Embassy in Islamabad condemned the attack and expressed sympathy to the families of the slain soldiers.     "Terrorism is the common pain of the two countries and the two Muslim nations have sacrificed precious lives in the fight against this plague," the Iranian Embassy said on Twitter.     "Undoubtedly, strengthening the joint cooperation between the two countries will prevent terrorist groups from achieving their sinister goals," wrote the Iranian diplomatic mission.    Pakistani Prime Minister Shehbaz Sharif expressed “grief and sorrow over the martyrdom” of the security personnel in the terrorist attack, his office said in a statement.  No group immediately took responsibility for Saturday's attack, the second incident this year in Baluchistan, where ethnic Baluch separatists routinely target Pakistani security forces.    In mid-January, four Pakistani troops were killed when a military convoy patrolling along the more than 900-kilometer border came under an insurgent attack from across the Iranian side.     The outlawed Baluchistan Liberation Army, or BLA, routinely takes credit for attacks on Pakistani security forces. Officials in Islamabad say the group has set up sanctuaries in border areas of Iran, charges Tehran rejects.   The Global Terrorism Index, released in March by the Australia-based Institute for Economics and Peace, said that BLA was responsible for 36% of nearly 650 terror-related deaths in Pakistan in 2022, making it "the fastest-growing terrorist group in the world."    Pakistan, the United States, and Britain have designated the BLA as a terrorist organization.    Baluch insurgents claim to be fighting for the independence of Baluchistan, alleging extortion by the central government of the region's natural resources and discrimination against its ethnic Baluch population. Pakistani authorities reject the charges.     The sparsely populated province, which also shares a significant chunk of the country's nearly 2,600-kilometer border with Afghanistan, is at the center of a multi-billion-dollar infrastructure development project being funded by China in Pakistan under Beijing's global Belt and Road Initiative.
