Clock Multiplication vs Division: Which to Use and Why
ByThe Art of Verification November 8, 2023July 22, 2026
In short: Designs need many clock frequencies from one reference. Division is simple but only gives integer ratios below the reference and can pile up jitter across a long chain. Multiplication, usually via a PLL, reaches higher frequencies, supports non-integer ratios, and often has lower jitter, which is why it suits high-speed links, CPU cores,…

Clock Monitors in SoC Verification
ByThe Art of Verification August 5, 2021July 26, 2026
In short: A clock monitor is a reusable SystemVerilog/UVM component that watches a clock signal and automatically checks its frequency, duty cycle, and on-the-fly switching, and flags glitches or timeouts. Because it is built as a uvm_monitor inside a uvm_agent, you can plug it into any UVM environment and verify complex clock systems without writing…
