I want to make local SKILL procedures, so they can be used inside pcell code.
I have made some custom Pcells, that use a set of custom procedures. Is there a way to easily embed these procedures inside the pcell code, so that they can still be used by calling the procedure with it's arguments, but that they only exist inside the Pcell?
Hello!
I am trying to use the command rdbWriteToFormat to save my output data and later use in matlab. But when I run the script it does not create the file and I am not sure why.
This is my script
Hi,
I have generated a layout using Innovus. Once I transfer it into Virtuoso, all the labels that are created have the Purpose of "drawing." In order for the Calibre LVS to pass, these labels need to have the Purpose of "pin." For large designs, I would like to avoid manually changing each label and was wondering if there are any SKILL scripts that I can reference to change each label Purpose from "drawing" to "pin." Hopefully, this question has not been asked before.
Regards.
Hi there,
In some skill code to process simulation results I get few warnings like below.
WARNING (OCN-6038): Results variables are not available for /path/to/.../dir. Use results() for a list of available results.
Because there are many lines of code (written by multiple users) I couldn't identify what line generates it.
Did some search/grep for selectResult() and pv(... ?result ...) calls but none of them is using "variables" results.
Any idea about how to identify the procedure(stacktrace) that generates the message?
Any other skill/ocean procedures that may directly access "variables" result?
The only idea that I have now is to do some debug printing in various places in the code.
Thank you,
Marcel
Recently, when doing my layout, the LSW window often cannot be edited, no matter using mouse scrolling or keyboard, only reboot the CIW (IC614) can make it work.
Dose anyone know how to solve this problem? Thanks.
Hello
I have tsmc13rf pdk .I add it into virtousu (6.16-32bit) without problem but I want to use virtousu (6.17-64bit) when I add this pdk into 6.17
I receive this error in icw =
*Error* loadContext: could not open file "/home/disk/simulation/TSMC130_PDK/tsmc13rf/../skill/64bit/pdkUtils.cxt"
there isn't any 64bit folder in skill library
is there any way to convert skill for virtousu 6.17-64bit
Can this error message be ignored?
Another seemly simple request that I cannot find the easy solution
1. I create a path : leCreatePath(...info...) and it returns a database ID
2. I need to get that ID to use in my next command but don't see how.
You would think that ID is stored in a stack or something.
I could always get it out of the CDS.log file but that seems ridiculous

Hi all,
I have the following problem. I want to run my simulations via an ocean script and want to read some currents for some subcircuits out of the psf file later. This all works in principle. The only problem I have is that the currents of subcircuits are stored by pin order rather than pin name by default. I know that I need to change the save option "useterms=name" to get the wanted result. However the ocean function: saveOptions() does not support the 'useterms option. What to do now?
Thanks for your help
Hello,
Is it possible to set a bold font type for text in "hiCreateDisclosureTriangle", like in "OBJECTS" and "GROUPS" of the attached image?
Thank you

In schematic, there is a wire with net name of "net01". One end of the wire connects to an instance and the other end of the wire is floating. I'd like to add a pin with same net name "net01" on the floating end of the wire. What I want like this: select the wire first, then run a skill, and the skill will add a pin named "net01" on the floating end of the wire. How to realize this with a skill script?

Hello everyone,
I am trying to automatically add some global variables and design variables when a new maestro view is created. It was quite easy to do it with ADE L using "asimenv.designVarSetting", however I could not find a straightforward method for maestro views.
I used a solution suggested by Andrew in another post. I used "createdTest" trigger to add the design variables after a new test is created. Here is the SKILL code;
procedure(CCFaddTestCreatedTrigger(sessionName)
axlSessionConnect(sessionName "createdTest" 'CCFtestCreatedTrigger)
)
procedure(CCFregCreatedTestTrigger()
axlSessionRegisterCreationCallback('CCFaddTestCreatedTrigger)
)
procedure(CCFtestCreatedTrigger(sessionName testName)
printf("> ADE Window Session %L is loaded\n> Test %L is created\n" sessionName list(testName))
maeSetVar("myvar" "1" ?session sessionName) ; Add Global Variable
maeSetVar("myvar" "1" ?session sessionName ?typeName "test" ?typeValue list(testName)) ; Add Local Variable to Created Test
)
The problem here is that the global variable is added but the design variable is not under the new created test.
I tried adding the design variable after the maestro view is created and loaded by running the following code in CIW;
sessionName=axlGetWindowSession()
openedTests = maeGetSetup(?session sessionName)
maeSetVar("myvar" "1" ?session sessionName ?typeName "test" ?typeValue openedTests)
and this method adds the design variable.
What am I missing here? Is there any better way to automatically add some global variables and/or design variables when a new maestro view is created?
Kind regards,
Naci
Hi,
Can somebody share me a script to find all uncolored(grey color) metals/vias in layout for latest technology nodes.
same can be done through violation check under multipatterning tool bar. But is taking more time for bigger layouts.
So can some please help me.
Thanks in Advance.
Dear all,
I came across a tricky situation when running the graphical interface of Cadence at the server's background and would like to ask help here.
I want to perform MC simulation on my design, which is very time consuming and hence I want the Cadence to run in the background.
I used screen session that runs Cadence. Then I detached the session and closes the Cadence graphical Interface.
However, when I re-attached the screen session again, I got the following error:
Hello all.
Let's say that I define a method.
The method does have the ability to qualify the arguments' class, when defining the argument.
However, any child of the class would pass too.
Is there a way, in the definition of the arguments, to qualify just the class, and not its' children?
Thanks.
I need to update a pcell parameter in a layout; specifically the pcell revision parameter. I would like to open the layout and update all the instances from the process library to the latest revision. I have included the following code that seems to work but I wanted to ask if there is a safer way to update this parameter and also if there is anything I'm omitting in the update process that may be a problem. I know that different pcell revisions have new layers/parameters that are added and I'm thinking there might be another step I'm missing. Note: this code assumes that the defValue param is the latest rev.
procedure( updatePcellRevs( lib cell view pLib)
let ( cv targetObjs paramIQ )
cv=dbOpenCellViewByType( lib cell view "" "a")
targetObjs=setof(x cv~>instances x~>libName==pLib)
if( targetObjs then
foreach( inst targetObjs
if( paramIQ=cdfFindParamByName(cdfGetInstCDF(inst),"pcellRev") then
if( paramIQ~>value==paramIQ~>defValue then
printf("No update needed.\n" nil )
else
if( cdfUpdateInstSingleParam(inst,paramIQ) then
printf("Changing \"%s\": %s --> %s\n" paramIQ~>prompt paramIQ~>paramIQ~>value paraIQ~>defValue )
else
printf("ERROR --> Parameter update failed!\n" nil )
); close if
); close if
); close if
); close foreach
); close if
dbSave(cv)
dbClose(cv)
); close let
); close procedure
Recently,I need to create the pcell using skill in virtuoso.
I want to know where I can understand these function,eg:dbOpenCellViewByType,dbCreateParamInst.
I have queried many docments,eg:SKILL Language Usere Guide,SKILL Language Reference.but its useless.
I also try to open 'the skill finder' from virtuoso,but its no response,maybe my cadence is not intact.
And,I find that maybe the doc 'Design Framework II SKILL Functions' is useful for me.But i don't find it.
Thanks for your help.

I am learning pcell creation , so I started out with this basic structure, a metal resistor.
problem : when the pcell is FIRST placed into a layout cell , the parameters for "metalLayer" and "squareSize"
I can address them and change them with css()~>metalLayer = some layer, or, css()~>squareSize = something.
If after they are first placed, I type in CIW : css()~>metalLayer <ret> the value returned is nil.
I cannot query the value of the parameter. Not until I type something like ,
if(!css()~>metalLayer then css()~>metalLayer="metal2" )
Why is that and how can I make visible the parameter value as soon as the instance is placed ??
(current cadence version 18 )
TIA. Malcolm

)
; Define the contents of this cellview.
let(()

Hi Cadence -
I created a new pcell and gave it 5 parameter values. ( param1 thru param5 )
I thought it was going to be easy to feed a new value to the pcell with replaceable text string where I concatenate a string
with a count number:
myPcell = car(selectedSet() )
count=1
while(count< 6
myPcell~>concat("param" count) = newValue
count = count +1 )
When I do this I get a *error* getsgq: arguement 2 should be a string or symbol
I've also tried myPcell~>strcat("param" count) and gotten a similar error.
How can I address the parameter name with replaceable variable names ; is this possible ?
thanks.
Hello,
I am trying to connect two metal nets (objType~>path).
if both metal net layers are same then simply align nets abutted.
if nets have different metal layers then check if metals layers can be connected using VIA .
eg if metals layers are M1 and M2 then connect using VIA1 taking via's min. width and min. enclosure by metal from techfile,
