UPF Overview Part II
Posted by Godwin Maben on January 2, 2008
Wish you all a very Happy and Prosperous New Year. Hope you all had a good holiday season.
In the last post we saw how UPF answers our questions with respect to the power behaviour of a design. Today lets look at how the various commands in UPF are catergorised.
(1) Power Domain Related
create_power_domain
(2) Power Supply/Nets related
create_supply_port
create_supply_net
connect_supply_net
set_domain_supply_net
(3) Special cell related
set_level_shifter
set_isolation_control
set_isolation
set_retention
set_retention_control
map_retention_cell
(4) Power Switch
create_power_switch
(5) State Table
add_port_state
create_pst
add_pst_state
(6) Utility Commands
In the next post, we will discuss functional verification using UPF, the first aspect of a design flow.
Once again, wish you all a very Happy and Prosperous 2008 !
I have worked in the VLSI industry for 14 years as a digital IC designer. My recent work has been focused on low-power challenges associated with multi-voltage/multi-supply designs. The goal of this blog is to open a free exchange of ideas with regards to low power. Please participate!
