- Creating an arbitrary 'src' directory really doesn't help much... - Goal is to make each folder self contained - Make meta repos and individual repos have the same directory structure

ETRACE INTRODUCTION
|
|
=====================================
|
|
|
|
The "etrace" module is a simple parametrized logic analyzer that captures a set of input signals in dual ported memory. Captured values can be read out through a memory mapped interface. Each sampled value is stored together with a counter time stamp. The vector is sampled on the rising edge of "trace_clk".
|
|
|
|
## USAGE
|
|
1. Instantiate in block and hook up signals. Use the dv/dut_etrace.v as an example
|
|
|
|
2. Enable the tracer by setting the trace_trigger to high AND setting bit[0] of the ETRACE_CFG register(810F00000).
|
|
|
|
3. (sample signals for as long as you want)
|
|
|
|
4. Read back values through the mi interface: 810A00000,810A00004,etc
