Low Power Static Checks

There seem to be some confusion about types of checks that need to be performed on a Low Power Design. In the Low Power static check world, following 3 types of analysis can be done on a design, in addition to various other checks. (a) Critique Check     Power State Table is Golden here and […]

Supply Set Usage

We are so much used to having explicit supply nets and ports in the design as well as in UPF,  its hard to visualize how a hardware logic designer would code the UPF using supply sets.   For those of you who are not familiar with supply sets, here is a quick preview of the same […]

Multi-Voltage/Power Gated design and LVS

  Some interesting observation while running LVS on a power gated or a MV design. Here is quick preview on the problem description   As shown in the picture above if LVS is run on a Verilog netlist generated without bulk pin connections, bulk connections may not be correct from electrical perspective. More on how […]
