Layout XL: power router pt. 2

PNadeau

This is a second problem I have been having in the power router.  Has anyone encountered this before?

I'm trying to use the "Cell Rows" mode. I have placed some custom standard cells, set them as STDCELL in Edit -> Component Types, chosen a boundary and selected the GND net in the Navigator.

When I click run I get the following error: 

*WARNING*  No pins found on layer M1 for net GND.

The standard cells all have M1 pins on the ground and supply straps ("pin" purpose for both the pin and label).  I've also tried using the "drawing" purpose for the pin and "pin" purpose for the label, or both as "drawing" purpose, with no luck.

Perhaps I am using the tool incorrectly: If my cells are all exactly abutted, then the power and ground rows are connected across the cells already (power and ground straps built into the cell).  Ultimately I'm most interested in getting the "Via" mode of the power routing tool to route the vias from my power stripes (generated in the "Stripe" mode of the tool) down to the cell rows.  But the "Via" mode doesn't seem to recognize my custom cell rows because it is not inserting vias, hence why I tried the "Cell Rows" feature first, thinking it might only recognize rows generated by the tool....

Thanks in advance,

  • Hi Phil,

    I answered another question of yours on another thread.

    If the tech file is not setup correctly it may be the case of this problem as well.

    It is difficult without seeing data.

    Also, if the number of standard cells are not too large (less than a few thousand) then you may be able to use the Custom Digital Placer to do what you want. (row definition/power stripe generation and cell placement) followed by auto contact generation.

    But to really solve this it may be necessary to contact customer support
