nanosim works with hspice/ spice netlist files, right?
1) if you have the layout and the schematic as well as the RCX/ PEX extractor like assura and calibre, then the work will be very simple; you just extract your layout, and then by using config for hspiceD you can set up a post simulation with hspiceD simulator.
to get the hspice netlist, after you set your config file for hspiceD, just click the botton to generate the netlist in ADE, and save the neltlist as a *.sp file. later you run this file using nanosim.
2) if you only have a hspice post-sim netlist (as in my case), then you can either setup your simulation setting using your hspice/ spice knowledge to make netlist for the power supply, control voltage, input signal and so on; or , like in my case, you can first make a cadence model for that post-sim netlist (this is the purpose of the link i gave you), and then put all required voltage/ signal sources, then generate the hspice netlist, and then use the netlist in nanosim.
