Library characterization, Logic Verification, and Spice are the 3 categories.  The Logic verification implies that logic design is independent from physical design.  Other tools include compilation before simulation so the time for synthesis, P&R, STA is done for each design iteration.  It is a natural step when the design emphasis is based on inference.

Logic design was always a separate/first step in IBM design, so that is still evidently true.  Logic design is a human activity while synthesis, and the rest of physical design is an automated process.

The initial Design Automation in IBM was really a wiring program for PCBs.  This has matured to include SPICE and other process parameters, but still leaves Logic Design as a separate step.

It worked for me and todays tools annoy me because of the poor support for logic design.  I did logic design before there were simulators so we mentally simulated he logic and came up with HW that worked.

Good points all. IBM is promising more releases soon and SiCAD hopes to supply the complete design flow--hand-offs and all--but you're right all the pieces to the puzzle are not there yet. At the DAC show they will be supplying more information on how to hook it all together in booth 710.

A useful group of tools would lead from initial design to some kind of handoff. At the very least it would include the digital part (synthesis, simulation, STA) and an analog section (schematic, spice, extraction, LVS, DRC). The value is only there if the tool flow scripts and etc. can be provided to make it easy for the user to do his first run through and get the output needed for handoff.

The Sicad inc website does not have any active pointers at this point, I think the opportunity to do this kind of thing is similar for a lot of consulting companies since they understand the requirements. What is needed to make this work is automation of user input and feedback.

Thanks for the clarifiation. Yes, the cost comparison was between IBM's one-day license and the longer licenses required for Cadence/Synopsis. In fact, you can't do the whole job with IBM's tools, so you'll need those shorter licenses to do the part IBM can't. Even IBM itself used Cadence/Synopsys for the rest of the flow they said.

You're right about the simulation not being 70-to-90 percent--that  estimate was to show how Library Characterization (for synthesis, sign-off and power analysis), Logic Verification (to verify and debug VHDL and Verilog), along with Spice simulation, is becoming increasinly important as we go to advanced nodes--where the processes are still being tuned. For solid process nodes like 28nm, of course, the percentage is much lower. Thanks again for your comments.

"instead of a three-to-five year license agreement like the other EDA vendors"

Synopsys and Cadence both license their EDA tools for as short as a month, sometimes less.

 

"they are offering what they say is 70-to-90 percent of a typical EDA design flow"

A simulator is 90% of the flow? So synthesis, P&R, ATPG, STA, LEC, DRC & LVS are just 10% of the flow. Come on. Verification may be a large proporition of the effort, but not of the flow or tools needed.
