Hello,
I am trying to do a post-layout simulation of a ring oscillator to determine why there is a discrepancy between the simulated oscillation frequency and the fabricated chip. Unfortunately when trying to use Assura RCX to do the parasitic extraction, I am unable to run RCX because the run button is grayed out. I have a successful LVS with everything matching and no errors. The help menu regarding RCX simply says that after a successful run of LVS, I can reopen the run and "Once the run is opened, the Run RCX... item is enabled in the Assura menu." However, if I open the run, there is still no menu option called Run RCX, nor anything that mentions RCX. I also found that if I attempt to run Assura from avview, the avview Assura Form also has "RCX -> Run..." grayed out as well as "Setup -> RCX setup..." grayed out. Does anyone have any idea what is wrong with my RCX?
I have attached pictures demonstrating what I see.
Thanks,
G
