Examining Soldermask pads and Symbol Soldermask definitions.

March 28, 2019, 1:22 pm

No Venture license for Advanced DFx checking -  So, as a novice at SKILL I am writing a Soldermask check to look for padstacks that have inaccurate mask openings. I am further trying to see if "tented" padstack definitions are cleared by Symbol shape definitions on the mask layer(s) within the Symbol. However I am having trouble as I loop through each symbol pin - how do I find out if it has a mask shape above or below it?  I see the axlGeoPointInShape command, but I first have to get the shape.  I have gone through manuals, examples and publicly released code but my efforts have failed me.  What i've done so far isnt pretty but it works for the most part.... I'm doing testing with Place Bounds as a shape because I know all symbols have them, but I also know I am going at it wrong. Any help would be greatly appreciated. Thanks in Advance!

How can I perform auto format Cadence Skill, such as indent, align...

The official tools 'SKILL IDE' do not have this feature.

Sometimes my 1st edtion skill source code's format looks like a mess and it will take me a long time to do the code format work like indent,align ...

So my question :

Is there any plugins OR ways to do auto format Cadence Skill source code?

change radiobutton text dynamically

Hi

I'm currently working on a form where I would like to be able to change the radiobutton (Checklist) text dynamically.

Example. 3 radiobutton choices

- 1.0

- 2.0

- 3.0

If I then select 3.0 it should change to show

- 2.0

- 3.0

- 4.0

I've not found a way to do this, is it even possible?

Best regards

Ole

Warnings with axlSetFindFilter(?onButtons '("BONDSMART" "DYNTHEMALS" "INVISIBLE"))

April 2, 2019, 12:04 pm
$

Using 17.2S051.

I've adjusted the Find Filter many times but not seen this issue before. I'm not sure what I'm doing wrong but clearly something is borked.

I'm saving the Find Filter at the start of my program and then restoring it at the end. Typical stuff. But in this program I see the following in the console:

*WARNING* (axlSetFindFilter): Options are ignored for onButtons - "BONDSMART"
*WARNING* (axlSetFindFilter): Options are ignored for onButtons - "DYNTHEMALS"
*WARNING* (axlSetFindFilter): Options are ignored for onButtons - "INVISIBLE"

I'm using the typical method:

procedure(<function name>(<parameter(s)>)
let((...)
; save find filter
lt_enabled = axlGetFindFilter(t)
lt_onButtons = axlGetFindFilter(nil)

; allowing selecting only text; adding "invisible" applies for all layers so the entire board is updated
axlSetFindFilter(?enabled list("noall" "invisible" "text") ?onButtons list("noall" "text"))
;axlMsgPut("%L" lt_enabled)
;axlMsgPut("%L" lt_onButtons)

<do stuff...>

axlSetFindFilter(?enabled lt_enabled ?onButtons lt_onButtons) ; restore find filter

<return value>
)
)

I can see that the lt_onButtons variable in the function above contains the three offending values in addition to "SYMBOLS". Those items aren't in the UI so I'm not sure why they're being returned to me. Even moreso because I always get back those four items in a list, regardless of how I configure the Find Filter before running my function. Even if I uncheck all items in the Find Filter I still get those four elements returned to me. I do see only "Text enabled and checked so that part works, it's only the restoration of the Find Filter that is a problem (it is not restored now and stays with only "Text" enabled and checked).

While I could use member(), or one if it's related functions, to strip out the problematic list elements that's hacky and not future-proof. I don't get why lt_onButtons returns elements that have no checkbox.

I can run different functions I've written on the same board and only this function results in the warnings above so I'm quite sure it's me and I'm just not seeing my own problem. Other functions where I've adjusted the Find Filter do not give any warnings and, as far as I can see, properly restore the Find Filter settings. Oddly, I see "nil" for both lt_enabled and lt_onButtons when I print them to the console using axlMsgPut() in working functions but the Find Filter is properly restored so I've done it right (I guess?).

Other board files have exactly the same behavior, where this one function is giving me the same returned list regardless of Find Filter settings while the other functions work fine and return nil as mentioned above. So I don't think it has anything to do with the board file.

Any ideas what I'm doing wrong?

Dear All,
I am a CAD Librarian, wishes to learn skill programming to check the footprint parameters, like line width and package height, and design unit.  for the first attempt, I started to code for checking line width of assembly outline, and also need to report an error in case of line width not as per standard. code inserted below, To enhance this code if in case of a width not as per standard it supposed to report error location.

axlCmdRegister("assycheck" 'asscheck)

p = axlDMOpenLog("REPORT")
    
    foreach(line, allLines
