Design Specs of our I2C Master. 8-bit data frame. SCL uni-directional control only. 7-bit slave address. Supports both slow and fast modes. Single Master, Multi-slave. Complied with original I2C specs by Philips. Pure RTL code is used. So the IP is easily portable across all FPGAs.

An I2C bus needs at a minimum an I2C master and an I2C slave. The I2C master is a transaction initiator (a master can write-to or read-from a slave). The I2C slave is a transaction recipient (a slave can be written-to or read-from a master). I2C waveform. Here's how it looks on the bus.

But anything beyond that — including whether the master is accessing the correct addresses, writing the correct data The I2C bus is a simple way to connect multiple chips together, in particular FPGAs/CPLDs.

The I2C specification. chip I2C Master and Slave Macro capable of linking one CPU to one I2C-bus.

Obviously I'm not implementing a full i2c slave as that would sort of trivialize the behavioral capabilities of VHDL to my thinking (although one day a verified slave would probably be the best way to test a master).

TYPE i2c_master_states IS (i2c_idle, i2c_start, i2c_data, i2c_repeat, i2c_ack, i2c_stop); SIGNAL fsm_master : i2c_master_states := i2c_idle; -- initalise in idle. SIGNAL i_bit_counter : natural range 0 to 7 := 0; -- bits transmitted. SIGNAL i_tick_counter : natural range 0 to 3 := 0; -- clock ticks elapsed.

Of course in any I2C transaction, the master would transmit the start condition, address, r/w bit and slave would transfer an ACK and so on and so forth. Is there a "standard" testbench for this? I would expect there to be code with flexibility to create BFM for our slave with some modification and then do self checks to verify if our master is working correctly. transmitter and master receiver.

You need to start by determining exactly what it is you want to "verify". Obviously, I2C is a simple protocol, and writing a monitor that verifies that the protocol is not being violated (including timing measurements, if desired 1) is a relatively straightforward matter..
