I2S Verification IP provides an smart way to verify the I2S bi-directional two-wire bus. The SmartDV's I2S Verification IP is fully compliant with version Philip's I2S-Bus Specification June 5, 1996 and provides the following features.
I2S Verification IP
is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
I2S Verification IP
comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
- Features
-
- Complies with Philips I2S Specification June 5, 1996
- Full I2S Transmitter, Receiver and Controller functionality
- Supports up to 32 channels in transmit path
- Supports up to 32 channels in receive path
- Supports programmable word length 8,12,16,20,24,32
- Supports programmable padding
- Supports programmable bit reversal
- Supports left and right justified
- Both transmitter and receiver can either work with SCK as input or can drive SCK
- Supports programmable data rate on transmit path
- Can operate as master or slave in several configurations
- Master or slave mode as transmitter
- Master or slave mode as receiver
- Master mode as controller (does not transmit or receive data)
- Notifies the testbench of significant events such as transactions, warnings, timing and protocol violations.
- Status counters for various events on bus.
- Callbacks in transmitter, receiver and monitor for various events.
- Supports constraints Randomization.
- Built in functional coverage analysis.
- I2S Verification IP comes with complete test suite to test every feature of I2S specification.
- Benefits
-
- Faster testbench development and more complete verification of I2S designs.
- Easy to use command interface simplifies testbench control and configuration of master and slave.
- Simplifies results analysis.
- Runs in every major simulation environment.
- I2S Verification Env
-
SmartDV's I2S Verification env contains following.
- Complete regression suite containing all the I2S testcases.
- Examples showing how to connect various components, and usage of Master, Slave and Monitor.
- Detailed documentation of all class, task and function's used in verification env.
- Documentation also contains User's Guide and Release notes.
- Smart VIPDebug
-
Smart VIPDebug provides easy way to debug the I2S Verification IP
Protocol. This links waveform, log file with specs and makes debugging easier
Smart VIPDebug supports both VCD and FSDB files for debugging.
