i2c opencores

[Tomas]

Hi,

has anybody successfully used this core? What I need to do seems to me
really really simple: configure a couple of settings of a transceiver
(operation frequency, transmitting mode, etc.). I was asked to do this
with a i2c bus.

I'm stuck creating the test bench just to do some read/write test. Has
anybody a simple testbench example?

Help.

Tomas

ISSUE 176

Control an FPGA with I2C, by Roberto Ferrabone, p. 60

There is a good I2C test bench written in VHDL. This article also has a
very good description of the I2C protocol.

It is worth the $5 to get the back issue in print.
