i2s_avip

This project deals with the I2S protocol

Accelerated VIP for i2s Protocol

The idea of using Accelerated VIP is to push the synthesizable part of the testbench into the separate top module along with the interface and it is named as HDL TOP and the unsynthesizable part is pushed into the HVL TOP. This setup provides the ability to run longer tests quickly. This particular testbench can be used for the simulation as well as the emulation based on the mode of operation.

Key Features

1. It has 8,16,24,32 Serial data bits for each sample.
2. It supports both mono channel and stereo channel modes of communication
3. It has different sample rates. (8 khz to 192 khz)
4. It supports the Left justified (Codec) mode.
5. It has 16-bit, 32-bit, 48-bit, or 64-bit Word select period.
6. Mechanism to enable Serial data transmission, WS generation and Serial clock generation.

Key features for the TO DO

1. It supports the Right justified (Codec) mode and Phillips Standard mode.

Running the test

Using Mentor's Questasim simulator

cd i2s_avip/sim/questasim

# Compilation:  
make compile

# Simulation:
make simulate test=<test_name> uvm_verbosity=<VERBOSITY_LEVEL>

ex: make simulate test=I2sWriteOperationWith16bitdataTxMasterRxSlaveWith8khzTest uvm_verbosity=UVM_HIGH
