Path Off-grids

Patrick1982 over 14 years ago

Hi Everyone,

When using Assura with one of IBM's DRC rule files, I get off-grids whenever I have a 45-degree angle and the only way to fix this is to chop out the 45-degree path and place an on-grid 45-degree polygon in it's place.

I am in the process of trying to write up some skill code to easily fix this, which will basically consist of searching for all 45-degree paths, chopping the 45-degree path and replacing it with a polygon of the same layer. Does anyone have some skill code that is similar to what I am trying to do? I'm sure someone has come up with something already, and it would be a great starting base for me.

Thanks very much,

Patrick

Hi Patrick,
I have some code which I have written previously for working with 45 degree angles in shapes, paths etc. - it is not quite what you are asking for, but it could be useful in your task. Please send me a private email or message so that I can reply to your email and send the attachment (I am not comfortable sharing this code on the forum).
Best regards,
Lawrence.

Note too that if using IC61, you can create wires using "pathSegs" which solve this problem by special handling of the 45 degree segments. All centre line vertices and edge vertices end up on the manufacturing grid.

Andrew.

So, how to solve this problem in IC51 ??

Turbo Toolbox has a capability to create "Polygon Paths" which would solve this problem, I guess. See <ICinstDir>/doc/toolboxhelp/toolboxhelp.pdf

I sent the code mentioned earlier through a private email, in response to your request. I just wanted to post this so that others may know that you have the code and will be testing to see if it resolves the issue.
Regards,
Lawrence.

That last message was in response to a request from "SUEE" - I thought that replying to his message would show differently in the forum history, but it does not seem to.
regards,
Lawrence.

Lawrence, I am having a very similar issue with 45's. If I were to send you an email, would you be willing to share your code? It may help me get started in the right direction. Thanks! Rob
