which format is this PSpice or HSpice?
* Model format: SPICE3
It's level 1 model in your netlist, not so complicate, en. You can just use Level1_Model from ADS, then modify the parameters' values.
But if for Bsim3 model, for example, it will be so complicated using this methods because there are so many paramters needed to be filled. Device models are provided from foundry in Spice format, Cadence format, ADS format, etc... for different simulators.
simply
1 ) open a project
2) open new schamatic window
3) from file menu , select import
4) select spice netlist
5) from more options , select the nelist type "hspice" , spice 35 , and so on
6) check the box to translate it into ADS nelist file
7) ads will translate the model file , file with the same name but .net
8) in ur circuit put netlist include component , and browse the new model fiel generated by ads
and enjoy the simulation
khouly
thanks, i imported the netlist. but got an error durring the simulation:
Error detected by hpeesofsim during netlist flattening.
`X1.mm': Substrate doping is less than ni.
How can I ignore this error?
the netlist is:
