Wanna fix DRC notch violations? There you go…

DRC is something which (most likely) is supposed to fail in first instance. Let’s see what you do to fix them. In below eg. drc count is 25. Qrouter (an open-source router, which will be discussed in detail in webinar) is really good with some standard cell sets like the one which comes distributed with qflow, like OSU018, they are really nice one’s to work with. All the ports have nice squares, they don’t have these inside ‘L’ corners as shown below.

eFabless is back…with synth/PD/DRC/LVS…and a working CHIP

A working chip is all using opensource EDA tools (no more license fee). Of course, its taped-out in 180nm technology. But who knows, this might be just the beginning. Upcoming blogs will talk more about the commercial angle of this. Let’s see how it is going to benefit student/professionals/innovators community

Distributed timing analysis webinar

There are multiple places, we can introduce distributed computing to timing and major motivation is to speed up the timing closure. We have to analyze timing under different range of conditions, typically quantified as modes (test mode, functional mode) and corner (PVT). The number of combinations (timing views) you have to run is typically increasing exponentially with lower nodes. That’s where you need to need to distribute timing analysis across different machines.

RISC-V waterfall diagram and hazards

The above waterfall diagram is representing a sequence of instructions that are fetched from memory and how they progress to the various stages of pipeline. In the above diagram you got program counter (P), fetch (F), decode (D), register read (R), execute (E) and register write (W). We fetch one instruction at a time. Potentially, you can fetch multiple instructions at a time, which would be a super-scalar architecture.
