Title: Problem with ASSURA pin names Post by pinkfloyd on Jan 22nd, 2014, 10:02am Hello. I am using AMS hit kit and I noticed that the only way to create labels and pins is to go to hit kit utilities, create label and then use the tool create pins from labels. I did it but when I try to run the LVS, in case I do not connect physically the metals that have the same pin and label ( for example VDD) it does not work, even if they have the same label and pin. So, only when I connect it passes the LVS but when I want to import the cell in my whole design I have to remove the metals. What do you propose? Thank you in advance |

Title: Re: Problem with ASSURA pin names Post by Andrew Beckett on Jan 25th, 2014, 6:04pm That's not the documentation of the tool - that's the kit documentation. If using Assura for an IC61 release you can run $ASSURAHOME/tools/bin/cdnshelp and then search for ?joinPins. Alternatively (and this will work for Assura intended for use with IC5141 too), look at $ASSURAHOME/doc/assurauser/assurauser.pdf and search for ?joinPins. ?joinPins allows you to set up a virtual connection without having to strap it in metal yourself. Kind Regards, Andrew. |
