Question 1

What are the EDAUtils Expert Systems?

Accepted Answer

A rule-based judge for the violations that CDC, RDC and Lint tools report. For each violation it answers FIX_RTL, WAIVE, FIX_CONSTRAINT or NEEDS_REVIEW, with the rule that fired and a numbered derivation.

Question 2

Does it replace Synopsys VC or Siemens Questa static checks?

Accepted Answer

No. It judges what those tools report. It reads Synopsys VC (CDC, RDC, Lint) and Siemens Questa (CDC, RDC) report layouts, and its built-in finder lets you start from the RTL alone. The vendor layouts follow documented shapes and are not verified against licensed output.

Question 3

What do GREEN, YELLOW and RED mean?

Accepted Answer

They compare the Advisor and the Expert System for one violation. GREEN: both recommend the same action. YELLOW: they differ without contradicting, or only one side answered. RED: one says WAIVE and the other a FIX, or a side failed to judge. A WAIVE is the unified action only when both say WAIVE.

Question 4

Is a waiver ever applied automatically?

Accepted Answer

No. WAIVE is a proposal. It needs technical evidence, the designer's attestation with a written reference, and a methodology policy that allows it, and it counts only after the named approver signs. When evidence is missing the answer is NEEDS_REVIEW.

Question 5

Does it need the AI SDK or the FECAD flow?

Accepted Answer

No. The Expert Systems run with or without the FECAD flow and with or without the SDK. The independent bundle needs neither. The unified Advisor plus Expert System run is part of the SDK, in the FECAD Lead.

Question 6

How is it licensed and how do I get it?

Accepted Answer

It is a licensed feature named expert-systems. The SDK licence covers it, and the independent bundle ships its own licence. Request it through the download form at https://edautilsonline.com/download?tool=EdautilsExpertSystems.
