Hi Guys, This morning I have been able to read an OPUS generated hspice netlist into asimut. Everything is ok until asimut reaches the linking process. It dies because: Error 104 :input/output `adr 11` doesn't exist Error 104 :input/output `adr 10` doesn't exist Error 104 :input/output `adr 9` doesn't exist Error 104 :input/output `adr 8` doesn't exist Error 104 :input/output `adr 7` doesn't exist Error 104 :input/output `adr 6` doesn't exist Error 104 :input/output `adr 5` doesn't exist Error 104 :input/output `adr 4` doesn't exist Error 104 :input/output `adr 3` doesn't exist Error 104 :input/output `adr 2` doesn't exist Error 104 :input/output `adr 1` doesn't exist Error 104 :input/output `adr 0` doesn't exist Error 104 :input/output `ck 0` doesn't exist, but all these nodes do exist in the netlist. The names are different adr_11, etc. because node names in a spice netlist cannot have embedded spaces. What is the correct syntax for node names in a spice netlist?
