Wireless verification environment
A new test environment was unleashed for the verification of 3G wireless designs for cellular phones and other wireless communication devices. The environment features a 3G mobile station tester (MST) which is based on technology from Electrobit Ltd and is designed to test parametric and call processing functions.
The environment provides I&Q data directly from the tester to the emulated design, then back to the tester. This data is based on custom-generated files or data extracted from the Cadence Signal Processing Worksystem (SPW). Additional environmental channel effects can be added to the I&Q data by adding the Elektrobit channel simulator to the verification environment. The bit-error-rate (BER) analysis, provided by the 3G-MST, and interactive closed-loop power control testing enables design validation using real-world scenarios.
