12m FPGA prototyping sans partitioning

12m FPGA prototyping sans partitioning
by Don Dingee on 10-16-2012 at 9:30 pm

FPGA-based prototyping brings SoC designers the possibility of a high-fidelity model running at near real-world speeds – at least until the RTL design gets too big, when partitioning creeps into the process and starts affecting the hoped-for results.

The average ASIC or ASSP today is on the order of 8 to 10M gates, and that includes… Read More

Image RemovedAs described in DO-254, any inability to verify specific requirements by test on the device itself must be justified, and alternative means must be provided. Certification authorities favor verification by test for formal verification credits because of the simple fact that hardware flies not simulation models.Read More

I’ve used Aldec tools like their Verilog simulator (Riviera PRO) when teaching a class to engineers at Lattice Semi, so to get an update about the company I spoke with Dave Rinehart recently by phone. A big product announcement by Aldec today is for their ASIC prototyping system with a capacity range of 4 Million to 96 Million… Read More

SystemVerilog from Nevada?

When I think of EDA companies the first geography that comes to mind is Silicon Valley because of the rich history of semiconductor design and fabrication, being close to your customers always makes sense. In the information era it shouldn’t matter so much where you develop EDA tools, so there has been a gradual shift to a wider… Read More

I speak VHDL and SystemC, others speak Verilog and SystemVerilog … what do you speak?

Before getting into the core of the topic let me give you some round figures, engineers love numbers. Julian Lonsdale “European Sales Manager at Aldec” informed me at the Xfest Munich last month that Aldec carried out a survey to evaluate the usage… Read More

AVNET released their 15[SUP]th[/SUP] Xfest this year, a couple of months ago. It was here in Germany last week. It was a well organized event, rich with invaluable technical information and full of decent smart engineers and managers. If you missed it this year register for the next event as soon as you can.

It was a very successful… Read More

In April I blogged about a webinar on co-simulation hosted by Aldec and Tanner EDA where they showed how the RTL simulator (Riviera PRO) and SPICE simulator (T-Spice) had been connected together for IC designers wanting to do real AMS simulations.

The availability date of the co-simulation wasn’t clear, so… Read More

The big three vendors in EDA offer AMS simulation tools but what about simulation choices from other EDA vendors?

It turns out there are two privately held EDA companies that have done business since the 1980’s and have just integrated a Verilog A simulator with a SPICE circuit simulator. The two companies are Aldec with a … Read More

Verilog History
Prabhu Goel founded Gateway Design Automation and Phil Moorby wrote the Verilog language back in 1984. In 1989 Cadence acquired Gateway and Verilog grew into a de-facto HDL standard. I first met Prabu at Wang Labs in 1982 where I designed a rather untestable custom chip named the WL-2001 (yes, it was named to honor… Read More
