rcOut: ERROR: (ENCEXT-2900)

Clidre

Hello,

I'm doing (my first) digital design flow and I'm using cadence encounter v14.26-s039_1

After the streamout, I wrote the .sdf files and then I wanted to write parasitic files for each corner, using rcOut command.

I defined 3 corners in my .view files called rc_nom, rc_best_m55c, and rc_worst_125c

When I type the following command:

rcOut -spef results/blockS.rctyp.spef -rc_corner rc_nom

I got the error:

**ERROR: (ENCEXT-2900): Unable to find rc-corner name 'rc_nom' in the active rc-corner list:
rc_worst_125c
rc_best_m55c
**ERROR: (ENCEXT-3185): Call extractRC again.

Could you please help me to see what's wrong?

Actually I don't know the usage of these .spef files... I know I can use the .sdf for simulations, but I don't know how to use these .spef. Anyway I don't know why it says that rc_nom is not an active corner if I defined it in the .view file.

Thanks a lot!!!!

  • I found that the corner has to be activated with with set_analysis_view, so now I'm using the following:

    set_analysis_view -setup {blockS_max_setup_125c} -hold {blockS_min_hold_m55c}

    extractRC

    rcOut -spef results/logic_.rcmax_125c.spef -rc_corner rc_worst_125c
    rcOut -spef results/logic_.rcmin_m55c.spef -rc_corner rc_best_m55c

    set_analysis_view -setup {blockS_typ} -hold {blockS_typ}
    extractRC
    rcOut -spef results/logic_.rctyp.spef -rc_corner rc_nom

    It seems to work.

    If you have suggestions feel free to add your comments.

    Thanks
