Chisel Things for OFDM

OFDM

This repository contains some blocks useful for making OFDM transceivers. This includes:

• Autocorrelator
• CORDIC (pipelined and iterative)
• Divider
• Filters
• NCO

as well as some higher level blocks that combine these to do useful OFDM things.

src/main/resources contains some traces from the ADI board that are useful for testing.

Running

To generate a synchronization block, run

sbt "runMain ofdm.GenerateSyncVerilog"

Testing

To run a test of the synchronization block and generate a nice plot, waveforms, etc., run

sbt "testOnly ofdm.SyncSpec

The waveform will be located at test_run_dir/ofdm.SyncSpec{RandomNumber}/Sync.vcd.

ofdm's Issues

Use chisel's `javacOptionsVersion` and `scalacOptionsVersion` in build.sbt

test failed

Hi authors，
I test failed when I try "testOnly ofdm.SyncSpec".
My verilator version is "Verilator 4.008 2018-12-01 rev UNKNOWN_REV".
How can I solve this problem? Thanks in advance!
Is it because of dependency?

emmm... Besides, 'IterativeCORDIC.circularRotation' and 'IterativeCORDIC.circularVectoring' also failed.
