Our soi DeCap with 5 terminals (VBGP/VBGN is the 5th terminal) share the same power template with standard cells, however, the leakage for DeCap is 0 value while standard cells get leakage power like 0.22345. Could you please help me find where the problem might be and how could I fix it?
Our lib goes like this:
cell (DCAP4_liberate) {
area : 0;
cell_leakage_power : 0;
pg_pin (GND) {
pg_type : primary_ground;
voltage_name : "GND";
}
pg_pin (VDD) {
pg_type : primary_power;
voltage_name : "VDD";
}
leakage_power () {
value : 0;
related_pg_pin : VDD;
}
}
Our char.tcl goes like:
set_operating_condition -voltage 1.8 -temp 25
set_var extsim_exclusive 0
define_leafcell \
-type pmos_soi \
-pin_position { 0 1 2 3 4 } \
ph
define_leafcell \
-type nmos_soi \
-pin_position { 0 1 2 3 4 } \
