encounter crash when placing

soc encounter techsite error ?

When I use SocEncounter to place the imported design,it crash every time,and tell me the internal error(SEGV),anybody have the same problem?
(soce 3.1 under rh 7.3)

soc encounter terminated by internal

:?: the error occured at end placement, why?

encounter crash partition

If LEF file only has two routing layers (metal1 & metal2), SOC encounter will crash when it want to place the cells. This is my observation. I do not know why. I have exactly same problem and I do not know how to fix.

how to route using to metal layers in soc encounter.it uses 3 metal layers .does any body have a solution to this.

it is common software bugs. you can update encounter. the current version of encounter is 4.1 user3. it is much faster than old version.

hi,
In any Unix flavour there is a command "TRUSS" by waching truss window uyou can be more specific about the reason why it is failing?
Syntax: $truss ./a.out

Try to update SOC Encounter or apply the patches from cadence.
