How to create a Verilog-a cell view from scratch

Purbayan

Hi, I want to create a Verilog-A cell view from scratch and after creating cell view I also want to create a symbol also from it

Right now this is what I have tried and I have faced these errors

deNewCellView("DV_TB_L1" "TestCell" "VerilogA" "VerilogA" nil)
*WARNING* (DEBASE-102032): _deOpenLevel: Cannot determine view type for cellview "DV_TB_L1 TestCell VerilogA"
This data is not registered in the data registry
*WARNING* (DEBASE-102076): __deValidateViewType: viewType "VerilogA" is not registered.

from this article( What is the simplest way to create a textual view like verilog veriloga verilogams vhdl systemverilog dspf using SKILL?) I also tried this but this is what I am getting

obj=ddGetObj("DV_TB_L1" "TESTCELL" "veriloga" "verilog.va" nil "w")
*WARNING* ddGetObj: File 'verilog.va' does not exist in the data registry, cannot create it as the master of the view '/TESTCELL/veriloga' in lib 'DV_TB_L1'
nil

Please help me with this

Also it will be appreciated on how to edit a Verilog-a file once it have been created with proper procedure

Thank you in advance

  • Hi

    I think your issue is that viewType "verilogA" does not exist in cadence, it is probably refering to viewType "netlist" what you need,.

    viewType=case(viewName ("layout" "maskLayout" ) ("schematic" "schematic") ("symbol" "schematicSymbol") ( t "netlist"));=> "schematicSymbol"

    Using deNewCellView would open an interactive window - if that's what you want, then you need to use "text.veriloga" as the viewType:

    deNewCellView("opamp090" "testva2" "veriloga" "text.veriloga")

    If you want to batch create the view, you could use the code in my article: How to create a text cellview using SKILL and then:

    tcv=CCSopenTextCellView("opamp090" "testva3" "veriloga" "a" "text.veriloga")
    fprintf(tcv->port "`include \"constants.vams\"\n")
    fprintf(tcv->port "`include \"disciplines.vams\"\n")
    fprintf(tcv->port "module testva3(a,b);\n")
    fprintf(tcv->port "endmodule\n")
    CCScloseTextCellView(tcv)
    ; check the cellView and create the OA shadow database
    vmsUpdateCellViews(?lib "opamp090" ?cell "testva3" ?view "veriloga")
