When floor planning (FP) and place & route (P&R) tools took over from custom layout tools for standard cell based designs, life became a lot better for designers of large digital chips. The beauty of the new flows was that all the internals of the standard cells and many IP blocks were hidden from view, lightening the load … Read More
Functional and physical verification are easily the two long poles in most IC product developments. During a design implementation cycle, design teams tend to push physical verification (PV) step towards the end as it is a time consuming process and requires significant manual interventions.
In the traditional… Read More
Design process retargeting is acommon recurrence based on scaling orBOM(Bill-Of-Material) cost improvement needs. This occursnot only with the availability of foundry process refresh to a more advanced node,but also to any new derivative process node tailored towards matching design complexity, power profile or reliability… Read More
Being new in Ottawa and trying to get some momentum towards automation in full custom layout I was telling industry people that I am interested to work with everybody to move this agenda forward. My Director of Engineering at that time, Peter Gillingham, took me to visit Carleton University in Ottawa. One of his professor friends,… Read More
One might be tempted to think that technology driven gains in computer performance might be enough to keep up with the needs of design and verification tools. We know that design complexity is increasing at a rate predicted by Moore’s Law. We also know that the performance of the computers used during IC development benefit from … Read More
Chip designers are familiar with the additional physical design checking requirements that were incorporated into flows at advanced process nodes. With the introduction of optical correction and inverse lithography technology applied during mask data generation, and with the extension of a 193nm exposure source to finer… Read More
Back in the day the Dracula tool from Cadence was king of the DRC and LVS world for physical IC verification, however more recently we’ve seen Calibre from Mentor Graphics as the leader in this realm. Cadence wanted to reclaim their earlier prominence in physical verification so they had to come out with something different… Read More
A few weeks back I wrote an article mentioning that Mentor Graphics has been quietly working on solutions for photonic integrated circuits (PICs) for some time now, while one of their competitors has recently established a photonics beachhead. One of the most common challenges for PIC designs is their curvilinear nature, thus… Read More
Every time the industry transitions to a smaller process node IC design software undergoes extensive updates.
I talked to a couple of experts in physical design at Mentor Graphics about what is involved in making place-and-route software ready for a new node. This is what I learned from Sudhakar Jilla, the IC design marketing director… Read More
After reading previous SemiWiki coverage on Dassault Systèmes and their ENOVIA Pinpoint solution, one big item seemed missing: how does this thing actually work? With all due respect to our other bloggers who covered when Dassault Systèmes acquired Pinpoint from Tuscany Design Automation, why Qualcomm is using Pinpoint, and… Read More
