In previous projects I used multi-mode analysisOriginally posted in cdnusers.org by clsantos
and CTE report mode (SOC52). I generate best and worst
case parasitc files for STA and also MIN and MAX
delay files (SDF). I used the following commands:
rcOut -worst -spf file_name_worst.spf
delayCal -sdf file_name_worst.sdf
rcOut -best -spf file_name_best.spf
delayCal -sdf file_name_best.sdf
But now I'm using SOC62 and multi-mode
multi-corner analysis and the above commands does
not work anymore. To generate parasitic files I'm
rcOut -rc_corner WORST -spf file_name_worst.spf
rcOut -rc_corner BEST -spf file_name_worst.spf
It seems be ok. Is this the right way to get
parasitic files in MMMC?
And how to get min/max delay files (sdf) in MMMC?
Usign the command delayCal, the resulting delay cells are
quite the same between MIN and MAX sdf files (less than 15%). I think there is no effect on
delay calculation when switching between hold and
I tried use write_sdf but looking at the file
header, the process, voltage and temperature
values indicates that both sdf files are for
typical case (which is the default opCond).
Can anyone help me?
