hi Dave, all
I am using 17.2 padstack editor . How can i read the width & the height value using skill code?
I am having decimal points issues on custom shapes, when ever there is a shape with X & Y size which has a 3rd decimal as "5", it either rounds up or rounds down.Our standard setup is in 3 decimals.
Please advice how can i tackle this issue.
Thanks
How to find if the padstack in a design is used or not using Allegro Skill?
Thanks,
Kirti
When I try to parse a line in a file in XML format I get an error:
E- *Error* parseString: argument #1 should be either a string or a symbol (type template = "SS") - ("global_min_aper")
The code I am using is:
axlExportXmlDBRecords("./temp_params.txt" nil)
minWidth_port = infile("./temp_params.txt")
when( minWidth_port
while( param_line = gets(param_line minWidth_port)
if(rexMatchp("smooth_min_gap" param_line) then
println(list("Global aper raw value = " param_line ))
global_min_aper = nth( 1 parseString(global_min_aper "<>"))
println(list("Global aper parsed value = " param_line ))
);if
);while
);when
close( minWidth_port )
This is basically a copy of the code which works for me on a typical report text file .
Can anyone point out what I am missing here?
Thanks.
Hello,
I want to delete a padstack in Allegro design which is not used.
Is there an Allergo skill function to delete specific padstack?
Thanks,
Kirti
I am trying to create a skill function to automate updating the stackup in Allegro PCB Designer using an IPC-2581. The program will grab an ipc2581.xml file that was previously updated earlier in the skill program and import it into Allegro PCB Designer.
I have tried two approaches but both fail to meet my needs.
The first attempt was to make a system call to execute the ipc2581_in command.
board = axlCurrentDesign() ; test.brd
sprintf(command "ipc2581_in ipc2581.xml -x -o %s" board)
system(command)
The issue with this process is the stackup for test.brd in Allegro does not reflect the changes from the import once the import complets. The ipc2581_in function parses the xml file and the brd file. It then deletes the brd file and creates a new one (this is because they are both named the same thing). After the process is complete the skill function exits and I am returned to the PCB Designer window. Opening up the stackup window displays the same data that was there before the import. If I close the design (without saving) and open the board back up, the stackup will then reflect the changes from the import. For this process to work I would need to alter the above block of code to somehow refresh the board but I am unaware of a function that does this. NOTE: When you utilize the Cadence built in IPC2581 import function this is what appears to occur because the Cadence command window states
PC2581 In completed successfully, use Viewlog to review the log file.
Opening existing design...
My second attempt was to use the axlShell function to run the ipc2581 command but this also does not work. I can run
axlShell("ipc2581 in") ; note there is no underscore
which will open up the Cadence IPC2581 In Gui but that defeats the purpose of automating the process since the designer now needs to still manually complete the process. I also tried running something similar to attempt 1 but without luck
board = axlCurrentDesign() ; test.brd
sprintf(command "ipc2581_in ipc2581.xml -x -o %s" board) ;
axlShell(command)
I tried the code above using "ipc2581 in" which just opened the Cadence gui and ignored all the text after the word in and I also tried using "ipc2581_in" which resulted in Allegro complaining there is no such command.
Any help would be greatly appreciated!!
Thanks

Hi Dave, all
I have a code to check footprint prints in our library. In my code i will output it into a log file called MCL log file.
In the code i have pass/fail messages in which for pass messages, i want to color it green & fail message as red.
How do i do that. Below is a portion of the code.Hope anyone can help.
Thanks

Hi All,
I want to run a shell command shown below
reports "Component Report" nographic write
As we know axlshell doesn't allow double quotes inside so I am trying to concatenate with strcat, however I am facing a problem with the double quotes. I also tried with \”, but unable to build a string as shown above. Does anyone have an idea, how can a double quotes can be concatenated in a string.
Thanks,
Sanjeev
Hi everyone,
I would like to ask some help, I created skill program that will determine if there are swap pins. But the problem is when I try to test two different netlist from two different board its not working.
I am using netlist from export.
Hi Guys,
Does there any tool which can be used to develop the SKILL programs and shows some syntax error or some colour indication if a function or user define function is used?
Currently I use notepad++ to develop the same, however sometimes its very difficult to find a syntax error.
Thanks,
Sanjeev
Hi everyone,
Can anyone help me how to know if use xhatch thermal width is checked.
Or there is a property attached to shape to know this is checked
Or there is a API for this one. Thanks

I am trying to output shape reports for all etch shapes in order to check them for errors.
My foreach loop works for normal skill commands but breaks after the first pass when I use
my script to create a report:
l_etchShapes = axlDBGetShapes( "ETCH" )
foreach( _testEtchShape l_etchShapes
println(list( "Shape Layer 1 = " _testEtchShape->layer )) ;print for debug
axlClearSelSet()
axlSingleSelectObject( _testEtchShape )
axlSetActiveLayer( _testEtchShape->layer )
axlVisibleDesign( nil )
axlVisibleLayer( _testEtchShape->layer t )
axlSetFindFilter(?enabled list("NOALL" "SHAPES" ) ?onButtons list("ALL"))
shpInstOut = outfile("./shape_rep.scr")
fprintf( shpInstOut "scriptmode +w +i\n" )
fprintf( shpInstOut "setwindow pcb\n" )
fprintf( shpInstOut "generaledit\n" )
fprintf( shpInstOut "shape select\n" )
fprintf( shpInstOut "pick grid %L\n", car( _testEtchShape->bBox ))
fprintf( shpInstOut "pop shape report\n" )
fprintf( shpInstOut "setwindow text\n" )
fprintf( shpInstOut "save\n" )
fprintf( shpInstOut "fillin \"temp_shp_report.txt\"\n" )
fprintf( shpInstOut "setwindow text\n" )
fprintf( shpInstOut "close\n" )
fprintf( shpInstOut "done\n" )
fprintf( shpInstOut "setwindow pcb\n" )
fprintf( shpInstOut "generaledit\n" )
close( shpInstOut )
axlShell("replay ./shape_rep.scr")
println(list( "Shape Layer 2 = " _testEtchShape->layer )) ;print for debug
);foreach
Can anyone tell me how to keep the loop from being broken by the script?
Hi Group,
Is it possible to write some skill program to length match the traces? For example, I am looking for some sort of program which allows user to click on particular trace or traces and then tool add serpentine/bends to match the trace length with the total length property on the net.
Or if skill program is not possible then any other way to automate length matching process in the Cadence Allegro? If I have 1000 nets to match then it takes much time. Any suggestion or thinker? Thanks.
Hi, I'm trying to figure out how to do a few simple things in APD using SKILL.
1) create a new mcm project
2) import a die/BGA text file
3) create some shapes, vias, etc.
I can find information in the manual about how to 1) (I think) and 3), but not 2). Any hints?
Thanks!
Hello,
I am looking to control, from a SKILL script/form, the "Display Net Names Functionality" as given in the Setup>Design Parameters checkboxes:
In the documentation I found
axlDBDisplayControl('displayNetNames, t/nil)
But obviously it doesn't control the three checkboxes since it is only one parameter.
Anyone know how to do this?
Thanks
How does one search the documentation for specific functions?
For example, where is the documentation for ipcWait() ?
I need to make a utility in which only tester ref des will given as output when I input the nets.
For example: Net name +5v is input net and output will be J225 no capacitors, resistors, or any component ref des will appear.
Although Allegro generate net-list report but it shows ref des of all components in particular net path.
I would like to see what are all the class/sub class is used in the allegro footprint.
Is there anybody created a context skill and run to 17.2 version without getting any error?
or still not yet fix with the latest hotfix 30?
Thank you
Is there a skill file that will take an 8 mil trace on a 45 degree bend and create a mitered trace? If not, how difficult would it be to write a skill file to do this? I don't have any skill experience.
