The PathWave Advanced Design System (ADS) Channel Simulator first became prevalent when transient simulation (SPICE) couldn’t address the measurement of margin-to-mask for low BER, as demanded by high-speed link designs. It continues to be the industry standard for channel simulation today. Keysight’s W2308EP Channel Simulator Element has the widest range of vendor transmit/receive models. It ensures S-parameter models are handled accurately in simulation with proprietary algorithms.
PathWave ADS has tools for all your pre-layout design exploration challenges. You can calculate line impedances with the Controlled Impedance Line Designer and model via behavior with the Via Designer. You can optimize link performance with integrated circuit optimization. You can even understand where the signal is degraded with integrated time-domain reflectometry (TDR) analysis. With all of these tools you will be able to minimize impedance mismatches and improve your margins.
