Hi,
I'm designing a low power circuit with five power domains (TOP, PD1, PD2, PD3 and PD4).
I'm at the final stage of my low power implementation and when I was about to insert filler cells on my chip the tool only inserted them in four of the five power domains (PD1, PD2, PD3, PD4) leaving my TOP power domain unchanged.
When I tried adding filler cells on my TOP power domain with the command addFiller -cell SHFILL1 -powerDomain TOP I got this error:
**ERROR: (IMPSP-5110): No supply-net names for Power Domain 'TOP'.
Any ideas why? Anyone been through this? I have all nets defined in my UPF file. Besides this error I cannot add any power rings around the TOP power domain (what I do is place the rings around the core)
Thanks!
