Skill code to add instance

Yassin

Hi,

I want a skill code to add an instance in a schematic sheet.

I tried the following code but it hasn't worked

procedure(
abc(component)
schHiCreateInst("tsmcN90" component "symbol" "I0" 1 1)
mouseAddPt()
0:0
)

then i call this function using:
abc("nch")

I am new to skill so i expect that there are much better ways to do that.

by the way, what does Hi stands for in the word schHiCreateInst??

Regards,
Yassin

  • The "hi" refers to "Human Interface". These are the commands you find when you are interactively working in Composer or Virtuoso. For doing the same thing in Skill code, you want to look for commands without the "hi".

    You should be able to use schCreateInst or dbCreateInst. To be honest, I'm not sure what the difference is between the two.

    procedure(abc(component)
        ;First you need to get the master id of the cell you want to place
        mstr=dbOpenCellViewByType("tsmcN90" component "symbol"  "schematicSymbol" "r")
        schCreateInst(geGetEditCellView() mstr "I0" 0:0 "R0" 1)
    )

    Note the following usage info for schCreateInst. If you set the instance name to be nil instead of I0, then Cadence will automatically name the instance uniquely.

    schCreateInst(
    d_cvId
    d_masterId
    t_instanceName
    l_origin
    t_orient
    [ n_magnification ]
    )
    => d_inst | nil

    Creates an instance of the given master cellview in the specified cellview at the given location with the given orientation. You can specify the magnification to set for the instance. Although not fully supported, you can use this property to scale the appearance of an instance.
