Subject: New Cadence User Asks "So What's A Cadence Flow That Works Now?"
Hi John,
I'm trying to get a complete Cadence-based tool flow up and I'm confused by
Cadence's product line. In particular I'm referring to:
Preview Silicon Ensemble
DSM Silicon Ensemble
PKS (aka Silicon Ensemble PKS)
First Encounter
SOC Encouter
We don't have First Encounter, but we do have PKS 4.0, DSM SE 5.3, and
Preview (IC446).
All these tools have substantial overlap. It seems like Cadence is moving
towards First Encounter and PKS as the complete solution. That's great for
the future, but what about now?
We're doing semi-custom design. We have full-custom datapath and standard
cell control. We need to do floorplanning, synthesis, P&R, and chip
assembly. We want to do everything flat (but with clustering). There seems
to be a couple of ways to doing things, but I wanted to ask how others
have handled it.
BTW, we use multiple power supplies on the chip (with inherited connections
in Composer). How is the power connectivity information conveyed between
this new mix of Cadence tools?
