Transmitter FIR Output Waveform Simulation

In this notebook, a step-by-step walk through of a 3-tap TX FIR output waveform generation is done to demonstrate the very basic concepts of TX FIR and its impact to signals going through channels. Useful codes are packed into helper functions to be reused in the future to futher explore automatic channel adaptation schemes such as TX FIR, FFE, RX CTLE and DFE etc.

From S-parameters to Eye Diagrams

Wishing we all a Happy, Healthy, Wealthy and Prosperous Year of 2022!

In this notebook, I briefly walked through a bare minimum serial link simulation procedure and demonstrated each step in python for:

• Remote site S-parameter file loading, pre-processing and system impulse response(IR) extraction
• IR to single-bit-response (SBR) conversion (where IR is the general system impulse response of the channel while SBR is the output of the single-bit input after going through the channel which is data-rate dependent)
• Transient simulation through time domain 1d convolution (pay attention to the numpy and the scipy output differences in function call convolve(a,v,"same") mode)
• Simple and fancier eye diagram plots
