Tessent PLLTest

Tessent® PLLTest provides complete, parametric, embedded test for PLLs, DLLs, and clock signals. It can measure jitter, phase delay, duty cycle, frequency ratio, lock time, and lock range, all in less than 100 ms, including test set-up and on-chip comparison to test limits via the IEEE 1149.1 TAP interface.

Tessent PLLTest uses the Mentor Graphics unlimited time-resolution analysis (ULTRA) patented technology. One 4k-gate ULTRA module can test any number of PLLs, and a TAP controller (or IEEE 1500 WTAP) can interface to any number of ULTRA modules.

Features and Benefits

  • Jitter measurement with picosecond accuracy: Histogram or RMS, timing jitter (loop bandwidth sensitive), period jitter (VCO noise sensitive).
  • Phase error and duty cycle measurement with picosecond accuracy: Any number of outputs, any synchronous output frequency.
  • Lock time measurement: Any frequency deviation, single clock-cycle accuracy.
  • Design and test automation: RTL insertion and testbench generation, characterization and production tests, repeatability analysis.
