I am writing an Allegro SKILL program that needs to ignore power nets. So
I first coded it to look for the VOLTAGE property on a net and that
worked fine. Then I specified the VOLTAGE property using the
Constraint Manager and now I can't find the VOLTAGE setting in the design in
SKILL. Voltage is "General Property" and can't be put into an ECSET so I don't think the
various Ecset SKILL functions will work.
Any thoughts about how to get information from the "General Properties"
section of the Constraint Manager? Or get them back into the
design so they are really properties I can find the old way.
Try adding the voltage property to the net(s) instead of adding them as part of an ECSet.Open the General Properties worksheet in the Nets folder.You may then use some skill to find the VOLTAGE properties.For example something likedesignnets = axlDBGetDesign() ->netsignorednets = '()count = 0 foreach(xx designnets mynet = nth(count++ designnets) netprops = mynet -> prop -> ?? count1 = 0 if(netprops != nil then foreach(xx netprops pmember = nth(count1++ netprops) if(pmember == "VOLTAGE" then ignorenet = 1 ); end if ); end foreach ); end if if(ignorenet == 1 then ignorednets = cons(mynet ignorednets) ); end if); end foreach
Thanks. I tried putting it in the General Properties and couldn't see
it in the design. I just tried it again and now it works - like I
thought it did in the first place.
Weird. I hate it when things don't work as expect - then work as expected.
