problem with pcell with radio button

techrddyz

Hi all,

i am trying to make a PCELL using SKILL script. I want my PCELL to be able to turn on/off certain layers based on the radio button selected by users. In the following code, I draw m1, m2 and m3. If user selects uptoM1, only M1 should be on, and if user selects uptoM3, all M1, M2 and M3 should be on. I have a call back function, decap_metallevel() in the radio button CDF to turn on and off metal layers. 

However, this function doesnt turn on/off metal layers when i select different radio button. Does anyone see where the problem is??  

pcDefinePCell(list(ddGetObj("testbench") "decap_pcell_test_1_SKILL" "layout") 
    ((uptoM1 boolean "TRUE") 
(uptoM2 boolean "TRUE") 
(uptoM3 boolean "TRUE")
    ) 
    let((uptoM1 uptoM2 uptoM3 pcMember pcStretchGroup
   stretchOffsetX stretchOffsetY pcLib pcMaster pcInst

   )) 
(uptoM1 = (pcParamProp~>value))
if(((pcParamProp~>valueType) == "boolean")

  • Rudy,

    Your callback function was wrong. It's setting the boolean parameters to "true" and "nil" (I've no idea why). It should set them to t/nil as follows:

    ;select or unselect all based on SelectAll
    procedure(decap_metallevel()
     case( cdfgData->MetalLevel->value
      ( "uptoM1t"
       cdfgData->uptoM1->value = t
       cdfgData->uptoM2->value = nil
       cdfgData->uptoM3->value = nil
      )
      ( "uptoM2t"
       cdfgData->uptoM1->value = t
       cdfgData->uptoM2->value = t
       cdfgData->uptoM3->value = nil
      )
      ( "uptoM3t"
       cdfgData->uptoM1->value = t
       cdfgData->uptoM2->value = t
       cdfgData->uptoM3->value = t
      )
     );case
    )

    With that, it works fine.
