How use netlist and spectre_encrypt

yxHou

I am a new one for cadence, I would like to figure out the Usage process of a spectre_encrypt netlist.

  • How to import the encrypted netlist into a Library schematic
    • I can import the netlist without encrypt, but once I try to import encrypted netlist, cadence will through out some errors
    • I wonder I use this in a wrong way, but I can't find any reference to solve it.
  • How to use the encrypted netlist and other model to draw a new schematic

Can any body help me, thx.

    Thanks for your patience again.

    In fact, the message you show is what I meet, what I want to get your help is what can I actually do to deal with this problem.

    • If I need to encrypt, do I need to expose the interface like subckt for M0 and M1, only encrypt the content except the interface, and then define Model to correspond to M0 and M1?
    • If for an unencrypted netlist, how can I solve the problem of ERROR :
      • Either include the file containing the definition of `NMOS_VTH', or define `NMOS_VTH' before running the simulation.

    Presumably you have models for NMOS_VTH and PMOS_VTH somewhere in a file, and so you can just include these via setup->Model Libraries in ADE.

    You do not need to expose the interface for the subckt - although if you don't expose the interface you'll have to tell people what the interface is so that they know what order the pins need to be in. Given that the interface doesn't give much away and it's useless without knowing somehow, I'd probably just protect the contents not the interface.
