encounter Digital Implementation system tool - layout issue

hon cheong

I have two questions regarding the encounter Digital Implementation system tool.

1. Using the digital implementation system tool, after doing floorplanning, place and route, the layout view for the standard cells are in abstract form. how can I view the layout view of those standard cells?
(I have include .lib and .lef files in the digital implementation system tool prior to synthesis).

2.If I want to import the layout to virtuoso from encounter digital implementation tool, I first save the synthesis result in DEF file format. In the DEF In dialog box, I am required to fill in "used Ref Library Names".
While I am using IBM process and found the .lef and .lib files in the "ARM_IBM_130nm8RF_4.0 " folder, I am unable to find any other DFII library that contains all the standard cells. Is that supposed to have one library that contains all the layout views of the standard cells?

Thank you.

  • Hi Kari,

     Because we get the process file from IBM through MOSIS, and we are confirmed that we are not provided the standard cell GDS file. I guess when I am about to tape out, the vendor will merge the GDS file for me.

    Is there any other alternative to import layout from encounter into virtuoso without standard cell GDS file? I need to do DRC and parasitic extraction in Virtuoso. Is that possible to use DEF format without the standard cell GDS file? Please advice .

     

    Thank You.
