Subject: Is Cadence Trying To Break The DEF 5.2 PhysOpt/SE Interface ?
John, anon please.
I was at my customer's site last week to debug a DEF in/out problem between
PhysOpt and Cadence SE. It appears that in the latest version of SE, there
is no longer an option to output DEF 5.2; only DEF 4.9 and DEF 5.3 were
listed as supported. The problem, of course, is that DEF 5.3 contains
numerous syntax cases not in DEF 5.2 that cause Synopsys def2pdef to fail.
Some of these are: VPIN, SUBNET, CLOCKROOT, + USE CLOCK, + ORIGINAL.
It appears to be a deliberate attempt by Cadence to break the interface
between PhysOpt and SE. I can't say I blame them for trying.
