Why UPF ?

UPF is language invented to allow user to do Low Power checks parallel to design flow. With UPF user can do Low Power checks at all stages of VLSI flow. i.e From RTL ,Netlist, PG-Netlist. UPF is written at RTL stage . User needs to define the power intent of his/her Design in the UPF file. Then user will take his RTL design and UPF to Synthesis tools like DC . Synthesis tool will add Low Power cells to Netlist Design based on what user has written in his/her UPF.

  2. set_isolation and set_isolation_control are two different commands in UPF1.0. In UPF2.0, all the options/flags of set_isolation_control is merged into set_isolation (set_iso_control is also there). Same applies to retention

    -update support for UPF commands was not there in UPF1.0
