Dangling Via Report

Hi karthikeyank

 You can find dangling via by using tool\report\Dangling Line, Via and Antenna Report. You can also create code to do it, but I think there is not via's attribute named "unconnected".

Hi, 

Like Luan said, you can get this report from the report menu. However, if you want to do this by using skill, you can use the axlDBGetConnect() command. 

I.e. replace your

via_data_lp->unconnected

with

length(axlDBGetConnect(via_data_lp t))<2

which finds all vias with less than two connections

Thanks you..

length(axlDBGetConnect(via_data_lp t))<2 using this code I was able to get the vias with single connection. When I try this code the dangling vias are getting deleted but some unintentional vias are also getting deleted. I want to find the list of dangling vias from the vias list and delete them.If any suggestions .Please help me.

foreach(via l_vias
    len = length(axlDBGetConnect(via)); connections connected to via
    if(len == 1 then ; checks if via has 1 connection
            if(via->net->name != nil then ;checks if via has net name
                  via_loc = via->xy
                  axlDeleteObject(via)
              );endif
       );endif
);end foreach

Hi guy!

Try this :
axlCmdRegister( "dvr" `dvr) ;dangling_via_report
(defun dvr ()
originalVisible = axlVisibleGet()
designName = axlCurrentDesign()
design_path = axlGetDrawingName()
design_unit = car(axlDBGetDesignUnits())
Drc = 0

axlSetFindFilter(?enabled '(noall VIAS) ?onButtons '(noall VIAS))
l_vias = axlGetSelSet(axlAddSelectAll())
axlClearSelSet()

writeOutFile = outfile("./dangling_via_report.log" "w")
fprintf(writeOutFile, "Design name: %s\n", design_path)
fprintf(writeOutFile, "%s %s\n", "Date: ", timeToString(fileTimeModified("dangling_via_report.log")))
fprintf(writeOutFile, "%s\n", "-------------------------------------------------------------------------------------------------")
fprintf(writeOutFile "%-24s %-24s %-20s\n\n", "Via_NetName", "Via name", "Location")

foreach(via l_vias
if(length(axlDBGetConnect(via t)) == 1 && via->net->name != nil then ; checks if via has 1 connection
;axlDeleteObject(via)
fprintf(writeOutFile, "%-24s %-24s %L \n", via->net->name, via->name, via->xy)
Drc = Drc + 1
);endif

Luan
);end foreach

fprintf(writeOutFile "END OF FILE\n")
close(writeOutFile)

if(Drc > 0 then
logWindow = axlUIViewFileCreate("dangling_via_report.log", "antenna via report..." nil )
else
axlUIConfirm( "No Error found.")
printf("No error found\n")
if(isFile("dangling_via_report.log") == t then deleteFile("dangling_via_report.log"));end if
); end if count_drc
);end defun dvr
