Change color/width of selected net via SKILL code

Hi Luis,

I just tried the following and it seemed to work:

foreach(mapcar obj geGetSelectedSet() when(obj~>objType=="line" schSetWireColor(obj "green")))

for setting the selected wire segment(s) to be 'green' in color.

There is also a function schGetWireColor(). For the line thickness there is schSetWireLineStyle(), so combining this also:

foreach(mapcar obj geGetSelectedSet() when(obj~>objType=="line" schSetWireColor(obj "green") schSetWireLineStyle(obj "thickLine")))

Hopefully this is what you are looking for? You should be able to see the color names when manually setting the wire color. For thicknesses, the default is "solid", thicker is "thickLine2" and thickest is "thickLine" I think.

Regards,

Lawrence.

Hi Lawrence,

Thank you for your reply. This is certainly going in the right direction. However, this command would only change the color of the selected wire segment. My idea is to change the color of the entire net, -which is composed of several wire segments- when selecting only one of such wire segments.

I wonder if there is an environment variable such as schSetNetColor (or something similar) that allows the intended behavior. Ultimately the idea is to bind this behavior and the thickness modification to a key.

Hi Luis,

You can modify the code so that the first (arbitrarily) object in the selected set is used to find the net and then find the figures on that net, then for each figure that is a line ("wire segment") it has the properties changed for that segment:

foreach(mapcar obj car(geGetSelectedSet())~>net~>figs
 when(obj~>objType=="line"
 schSetWireColor(obj "green")
 schSetWireLineStyle(obj "thickLine")
 ); when
); foreach

Best regards,

Lawrence.

I should also point out (me being Mr. Pedantic) that the mapcar keyword is unnecessary here because you're not using the return value of the foreach. It actually costs more (a little) to collect the list of return values when using foreach mapcar, so unless you need the return values, there's little point in doing this. An ordinary foreach would suffice here.

Very true. I used the mapcar during development/testing to check the return values of the function inside the loop, but left it in. Sometimes I wrap the foreach(mapcar ... with a "forall" to gain the overall return value. Thank you for noticing that I'd left it in, it could cause confusion...

Thank you Lawrence!

Works like a charm.

But, how do i remove these coloring to get the default?

Choose "cadetBlue" for the color and "solid" for the lineStyle.

foreach(obj car(geGetSelectedSet())~>net~>figs
  when(obj~>objType=="line"
    schSetWireColor(obj "cadetBlue")
    schSetWireLineStyle(obj "solid")
  ); when
); foreach

Lawrence's suggestion does reset the color and line style overrides on the wire (i.e. it removes the info in the database with the override) provided that the color and line style match the info for the packet used for the wire. So strictly speaking you should do:

packetName=techGetLPPacketName(techGetLP(tf list("wire" "drawing")))
defaultLineStyle=nth(3 drGetPacket("display" packetName))
defaultColor=nth(5 drGetPacket("display" packetName))

Then in Lawrence's code you could do:

schSetWireColor(obj defaultColor)
schSetWireLineStyle(obj defaultLineStyle)

Andrew.
