Multi-power Domain Design

Designs with multipower domains are increasingly common in ICs for all type of communication devices such as mobile or networking equipment. PrimeSilicon can build and implement multi-voltage architectures with inherently complex ICs with tested design implementation flows.

• We have flow scripts suited to all EDA tools to manage multi-threshold CMOS switches to enable switching off certain portions of an IC when that functionality is not required, and then restoring power as needed.
• We ensure that the architecture is frozen and captures all the power constraints required for the chosen multi-voltage style in the IEEE1801 Unified Power Format (UPF) file.
• We do RTL synthesis and verification by using the UPF file, perform thorough power-aware functional verification. This will uncover any functional bugs, including failure to retain state information, improper sequencing, reset failure, activity in OFF states, and an unexpected 'always OFF' condition.
