Calibre PEX in Cadence

(1)Under virtuoso environment of the cell which needs to be extracted---XXXX for example, click “Calibre->PEX” on the tool bar.

For rule file blank, choose the directory: /ecad/TEK/TSMC18/Calibre/caliber.rcx.

Figure 1

(2) In the inputs items, choose to export GDSII file from layout, SPICE file from schematic, since the LVS process will also run in PEX. (Thus, PEX won’t pass until LVS pass). In the Outputs item, choose the extraction type between 5 items: (Figure 2). SVDB and Reports options can be chose according to your requirement. Attention here, change the

netlist format from “ELDO” to “Calibre”. (Figure 3)

(3) If PEX pass successfully, there will be a dialog block named “Calibre

View Setup” jumping out. In the “Cellmap file” blank, type in /ecad/TEK/TSMC18/Calibre/calview.cellmap, choose “schematic” in Cellmap View Type; click “ok” to create Calibre view for XXXX. (Figure 4) A Note will jump out alarming that n warnings and 0 errors are found.

(4)Create the test bench which will use XXXX cell. Create a schematic

view named sim_for_XXXX or so, and call for the symbol of XXXX in this schematic view, save it. Then, in library manager or CIW, click “File->New->Cellview…” click “hierarchy-editor” in editor blank or type in the cell view blank “config”. (Figure 5)

(5)A dialog block named “New Configuration” will jump out. Click “use

template” at the bottom, in the small dialog block jumped immediately, choose “spectre”, and click “OK”. (Figure 6)

(6) In hierarchy editor configuration block for config view of “sim_for_XXXX”, click XXXX item with the right key of mouse, and choose the view attracted, here is “Calibre”. Click the button of “update”---the eighth button counts from the left of the tool button to update the view. (Figure 7) The following simulation process remains the same as in schematic view.
