SLM Clock & Delay Monitor IP

芯片

Measure Delay Between Edges of a Signal

Synopsys SLM Clock & Delay Monitor (CDM) IP can be implemented in silicon with minimal area overhead. It doesn’t need any accurate high speed reference clock and provides accurate time delay measurement. It can be used for measuring clock duty cycle, memory access time, delay line characteristics, etc. It has IEEE 1500/1687 interface for connecting to test fabric. The SLM CDM IP is also available as an ISO 26262 ASIL-B ready product.
