    Equating multiple layout devices to a single schematic device




      I have a question which I hope some of you can help me solve.

      How do I equate multiple layout device structures to a single schematic device?

      I have tried *.EQUIV sw1=sw sw2=sw in the CDL netlist but it is not an acceptable format as the error I will get is:


      LVS Netlist Compiler - Errors and Warnings for "test.sp"
      Warning: Conflicting *.EQUIV specification for "sw" in file "test.sp" at line 6. "sw1" used, "sw2" ignored.
      The scenario is because:
      I have one schematic device which is a switch (sw).
      This switch can be drawn in any metal layer in layout, hence I have multiple layout devices defined in LVS device recognition statements e.g. sw1, sw2, etc. to represent the metal1 switch, metal2 switch respectively.
      Appreciate if I could get some tips.
      Thanks in advance.
