Could you please tell me what version of Primetime you use?
Our Primetime version is 2003.03.
I really can't use these commands in PT. I will check the new version
support or not.
Hi
I think set_ideal_net doesn't work in primetime. There was a STAR opened long time ago. synopsys didn't fix it yet (atleast until the version I use 2003.12-sp1)
You can use
set_load -subtract_pin_load 0.0 [get_nets "high_fanout_net_name"]
What this command does is ...
It sets capacitance value of 0 on that net and removes max transition and max capacitance limit. This behaves pretty much same as "set_ideal_net"
Why would you want to use set_ideal_net in primetime? It makes no sense to even run primetime on non-back-annotated parasitics, pre-high-fanout-net-synthesis netlist. At least thats my
opinion...
When doing Pre-Layout STA you must use these command for high-fan-out net,
in DC theses command are work,but in PT we must use anyother way to set these as ideal.
for example using set_load command .......
