Customised Unconnected net report

tmd63

Does anyone have or know how to make a customised unconnected net report?

I need to have a report that shows similar to the 'unconnected pins report'. But it also shows the distance of the unconnected pins (X1-X2 and Y1-Y2 for example, or even further [[X1-X2]^2+[Y1-Y2}^2]^0.5 so it gives the distance between the X1,Y1 and X2,Y2 positions).

I could import into excel and extract the information but this is long and involved and prone to errors, if there is an easier report method I would like to know how.

  • below is an example skill file 'custom_ucn.il"

    procedure((custom_ucn \@optional FileName)
    prog((outport OutputName NetCnt RatCnt Total startPin endPin String)
    if( FileName then
    (OutputName = strcat(simplifyFilename(".") "/" FileName))
    (OutputName = FileName)
    else
    (OutputName = strcat(simplifyFilename(".") "/ucn.rpt"))
    )
    if(isFile(OutputName) then
    unless(deleteFile(OutputName)
    (axlMsgPut "ERROR: could not remove existing file %s" OutputName)
    return()
    )
    )
    if((outport = outfile(OutputName)) then
    (Total = 0)
    foreach(net ((axlDBGetDesign)->nets)
    (RatCnt = 0)
    foreach(rat (net->ratsnest)
    unless( rat->pinsConnected
    (RatCnt++)
    when( eq(RatCnt 1)
    fprintf(outport "%s\n" net->name)
    )
    (startPin = car(rat->pins))
    (endPin = cadr(rat->pins))
    when(startPin && endPin
    fprintf(outport "From: %s.%s (%f %f) " startPin->component->name startPin->number xCoord(startPin->xy) yCoord(startPin->xy))
    fprintf(outport "To: %s.%s (%f %f) " endPin->component->name endPin->number xCoord(endPin->xy) yCoord(endPin->xy))
    fprintf(outport "Delta: (%f %f)\n" difference(xCoord(startPin->xy) xCoord(endPin->xy)) difference(yCoord(startPin->xy) yCoord(endPin->xy)))
    )
    )
    )
    (Total = Total + RatCnt)
    )
    (axlMsgPut "%d ratsnests written to %s" Total OutputName)
    else
    (axlMsgPut "ERROR: could not open output file %s" OutputName)
    return()
    )
    )
    )
    axlCmdRegister("custom_ucn" 'custom_ucn)


    Below is the allegro.jrl file showing how to load & run it:

    \i (00:00:06) generaledit
    \i (00:00:09) skill '`'load "custom_ucn.il"`''
    (00:00:09) t
    \i (00:00:15) custom_ucn
    \t (00:00:15) 2 ratsnests written to C:\Temp/ucn.rpt
    \i (00:00:16) generaledit

    and below is the output file contents:

    XDMA_EVENT_INTR0
    From: P2.17 (1281.000000 687.500000) To: R18.2 (1650.000000 430.000000) Delta: (-369.000000 257.500000)
    DGND
    From: P2.12 (1494.000000 537.500000) To: P2.10 (1494.000000 487.500000) Delta: (0.000000 50.000000)

    Would this work?

    (diffX = difference(xCoord(startPin->xy) xCoord(endPin->xy)))
    (diffY = difference(yCoord(startPin->xy) yCoord(endPin->xy)))
    (startPin = cadr(rat->pins))
    (endPin = cadr(rat->pins))
    when(startPin && endPin
    fprintf(outport "From: %s.%s (%f %f) " startPin->component->name startPin->number xCoord(startPin->xy) yCoord(startPin->xy))
    fprintf(outport "To: %s.%s (%f %f) " endPin->component->name endPin->number xCoord(endPin->xy) yCoord(endPin->xy))
    fprintf(outport "Delta: (%f %f) " diffX diffY
    fprintf(outport "Length: (%f)\n " sqrt( ( diffX * diffX) + ( diffY * diffY))

    I think it should work, but I would replace the last line with:

    fprintf(outport "Length: (%f)\n " axlDistance(startPin->xy endPin->xy))
