-tapcell_master
. Specify the master used as a tapcell.-endcap_master
. Specify the master used as an endcap.-distance
. Specify the distance (in microns) between each tapcell in the checkerboard.-halo_width_x
. Specify the horizontal halo size (in microns) around macros during cut rows.-halo_width_y
. Specify the vertical halo size (in microns) around macros during cut rows.-tap_nwintie_master
. Specify the master cell placed at the top and bottom of
macros and the core area according the row orientation.-tap_nwin2_master
. Specify the master cell placed at the top and bottom of
macros and the core area according the row orientation. This master should be
smaller than tap_nwintie_master
.-tap_nwin3_master
. Specify the master cell placed at the top and bottom of
macros and the core area according the row orientation. This master should be
smaller than tap_nwin2_master
.-tap_nwouttie_master
. Specify the master cell placed at the top and bottom of
macros and the core area according the row orientation.-tap_nwout2_master
. Specify the master cell placed at the top and bottom of
macros and the core area according the row orientation. This master should be
smaller than tap_nwouttie_master
.-tap_nwout3_master
. Specify the master cell placed at the top and bottom of
macros and the core area according the row orientation. This master should be
smaller than tap_nwout2_master
.-incnrcap_nwin_master
. Specify the master cell placed at the corners of macros,
according the row orientation.-incnrcap_nwout_master
. Specify the master cell placed at the corners of macros,
according the row orientation.-cnrcap_nwin_master
. Specify the macro cell placed at the corners the core area
according the row orientation.-cnrcap_nwout_master
. Specify the macro cell placed at the corners the core area
according the row orientation.-tap_prefix
. Specify the name prefix for the tapcell instances. The default prefix is TAP_
.-endcap_prefix
. Specify the name prefix for the endcaps instances. The default prefix is PHY_
.The figures below show two examples of tapcell insertion. When only the
-tapcell_master
and -endcap_master
masters are given, the tapcell placement
is similar to Figure 1. When the remaining masters are give, the tapcell
placement is similar to Figure 2.
