Any help appreciated:
I experience a very slow loadup on a layout in a CMOS technology.
The circuits are not very large but the CPU is pegged for hours.
To avoid any possibility of network bottlenecks, all cells referenced
have been copied to a local disk.
"iostat" "vmstat" are literally quiet durning this process and CPU is 100%.
No swapping, paging or anything unusual.
But it seems "icfb" is hung or looping.
Eventually the circuit will open up but could take up to an hour
depending on the relative size.
The same thing happens when closing the circuit (if "close Data" is used.)
However, if the same circuit is opened up again without exiting Cadence,
it will open up in a few seconds as though all the info is cached.
Hardware varies but generally are SunBlades (1000, 1500, 2000, 2500)
running Solaris 2.8 and 2.9 with patch clusters.
Same circumstances whether or not circuit and cells are networked
or local.
I'm not that familiar with the technology or layout but as the sys
admin, the bosses always think I did something with the network so
they come to me.
Anyone experience anything like this?
Thanks...GeorgeC
