B.1 add_pst_state
| Purpose | Define the states of each of the supply nets for one possible state of the design | |
| Syntax |
<b class="bold">add_pst_state</b> <i class="emphasis">state_name</i> <b class="bold">-pst</b> <i class="emphasis">table_name</i> <b class="bold">-state</b> <i class="emphasis">supply_states</i> | |
| Arguments |
<i class="emphasis">state_name</i> | The power state. |
|
<b class="bold">-pst</b> <i class="emphasis">table_name</i> | The power state table (PST) to which this state applies. | |
|
<b class="bold">-state</b> <i class="emphasis">supply_states</i> | The list of supply net state names, listed in the corresponding order of the -supplies listing in the create_pst command. | |
| Return value | Return a 1 if successful or a 0 if not. |
The add_pst_state command defines the states of each of the supply nets for one possible state of the design.
It is an error if the number of supply_state_names is different than the number of supply nets within the PST.
Syntax example:
create_pst pt -supplies { PN1 PN2 SOC/OTC/PN3 }add_pst_state s1 -pst pt -state { s08 s08...
