Synopsys SLM Process, Voltage & Temperature Monitor IP

Process, Voltage and Temperature (PVT) monitoring is critical to achieve reliable operation and optimum performance of advanced node (FinFET, GAA) semiconductor devices. Increasing transistor density, multi-die ICs and pushing silicon performance boundaries is making monitoring of PVT parameters throughout the silicon lifecycle a necessity. Based on the output of these monitors actions can be taken to optimize silicon health.

The Synopsys SLM PVT IP portfolio includes process detector, voltage monitor, temperature sensor, distributed temperature sensor, catastrophic temperature sensor and thermal diode.

Unique Modular Solution
Belonging to the Silicon Lifecycle Management (SLM) family, the PVT Monitor IP from Synopsys offers a high accuracy, highly featured and modular solution which can be tailored to the customer’s requirements. The well-supported monitoring solution for SoC designs is available from 28nm down to 3nm in both commercial and automotive grades.

PVT Controller and Driver
The PVT Controller is highly configurable and manages the subsystem of monitors, relieving the system control processor of many tasks associated with PVT monitoring. For a large die, multiple instances of the PVT Controller, each with its own subsystem of PVT monitors, can be instantiated.

A reference bare metal software driver is now also included with the PVT Controller Series 5 that is ISA (Instruction Set Architecture) agnostic and portable.
