But ,is there any compatiblity between GCF and SDC?
And i have noticed that SDC is the timing constraints from synopsys design compiler. If it is true, that means cadence will use synopsys constraint file format in its product : Encounter?
Re: Could GCF be supported by Enconter and Astro, other than
Yeap, in fact in the old days using SE & Ambit, you may use a utility to convert SDC into GCF format. But you should better check the Cadence "SDC" syntax and there may be some minor different from Synopsys DC in commands/constraints.
I've learned from Cadence's FAE that SoC Enc 4.1 is using SDC for timing driven P&R and there is no plan to support GCF in future SoC Enc releases.
If cadence really do so, there must be some reason .
But since there are littile different between GCF and SDC, i think it is not bad to learn GCF in SE first.
Thanks kctang.
