hspice coding help for different ground terminals

[rajee]

In Hspice coding,I want to define two different ground terminals in single file.
I am having two different blocks in my design each having different ground terminals.They should not share common ground.



how can I give two different ground terminals in a single file.

if given with different names it also ends up in common ground.

No problem with HSPICE: Just give them different names, one of them being "0". Or give them 2 different names, e.g. "GND0" & "GND1", and connect one of them directly to node "0" - either by a DC vsource with 0V, or by a 0Ω resistor. The other "GND" should have a connection to any other node of the circuit also - by one of the 2 above mentioned methods, or by any other device of your choice (resistor > 0Ω , or inductance).
