PERC

 PERC is a reliability verification platform, providing robust, full chip, sign-off quality checks in an integrated environment. From your first schematic, through SoC assembly, to the final layout, we are able to provide a repeatable, efficient and effective reliability verification platform capable of verifying your most challenging reliability issues.

the mix signal design, it is required to have different voltages to support each domain on the chip. However, designers have to make sure there is no signal line directly across from one voltage to another without any protection. Calibre PERC can help you to quickly find out if you have the right protections in your design.

Electrostatic discharge (ESD) events causes severe damage to ICs. Several protection schemes have been proposed to mitigate this damage. Double diode ESD network is an example of a very common protection scheme for Input signals. Calibre PERC High Level Checks GUI enables the description of these protection circuits in the form of a Calibre rule-check with minimum effort. 

Electrical overstress (EOS) is responsible for the vast majority of device failures and product returns. The use of multiple voltages increases the risk of EOS, so IC designers need to increase their diligence to ensure that thin-oxide digital transistors do not have direct or indirect paths to high-voltage portions of the design.

Multiple Voltage Design

MODERN TECHNIQUES                                                      Modern IC designs are heavily influenced by the need to minimize power consumption, particularly in the consumer electronics market. The devices' warmth, battery life, and the time it takes to switch on and off the functions of handheld devices are currently being reformed. Therefore, it becomes crucial to implement best practices in chip design to help reduce power consumption in SoCs (System on Chip). The power management of SoCs and RTL designs has a significant impact on the silicon's performance. Power-aware designs are used by industry to achieve power statistics. This blog focuses on multi-voltage design terms that can be used to assess the power performance of silicon in HDL coding. These facilitate the understanding of design parameters while implementing power-consciou...
