( ESNUG 392 Item 4 ) --------------------------------------------- [04/18/02]
Subject: Synopsys R&D Q&A To The SNUG'02 DC-Ultra Tutorial (Day 2)
42. Is compile_ultra supported as part of compile_physical?
Not currently. We are planning to support it in a future releases.
43. Could the finite state machine (FSM) optimization extract the logic
that is not part of the FSM by mistake?
The FSM logic consists of FSM flip-flops and associated combinational
cells. The extraction process knows which flip-flops are FSM; for
associated combinational logic, the process uses its own algorithm to
determine which cells are part of FSM. The new FSM flow has a more
sophisticated partition algorithm, which extracts less combinational
logic than the old flow.
44. Is there a report command for the FSM?
Yes: report_fsm.
45. Does the new data-path optimization require a Module Compiler
license?
No, it does not require a Module Compiler license.
46. Does compile_ultra support the auto-ungroup option?
Auto-ungroup is turned on by default for compile_ultra. You can turn
it off with the -no_autoungroup option.
47. Is SOLD for version 2002.05 available now?
It will be available with the release.
48. Is there an attribute to query from your script on what version of
the tool you are using?
There is no attribute to query; however the compatibility_version
variable can be used to determine the version you are using.
49. What about support for multiple operating conditions?
We are planning for multiple voltage support in a future release.
50. Current installation results in errors with the 64-bit executable
files. Is it being fixed?
We are not aware of this problem. Please check with your AC for
updates.
