 21 Jul 2005 3:46 problem in connecting power pad to core ring in encounter |
|

Dear all,
When i try to connect the power pad pin to the core power ring in SOC encounter, i found that there is no connection generated. The pin assignment of the power pad is as follow (grap from IO LEF file):
pin A (for connecting to core power ring)
pin vdd3o!, vdd3r1!, vdd3r2! (for connecting pad ring)
pin gnd3o! gnd3r! (for connecting pad ring)
I have set the global nets connection as follow:
pin* vdd3o!:All
pin* vdd3r1!:All
pin* vdd3r2!:All
pin* gnd3o!:All
pin* gnd3r!:All
And the core power ring's power nets are vdd! and gnd!, which are the power pins' name of the std cells.
Do anyone know what is the problems?
Thank you very much for your help.
Best Regards,
Market
