Check i2c slave

Hello,
I am developing I2C slave module on VHDL and I want to test it. Can you
recommend me some hardware/software that I can use as I2C master and execute
different I2C requests to test my module?

David.

I can't say they have a test bench, but there is a core available at

http://www.opencores.org/projects.cgi/web/i2c/overview

You may find that they have a test bench written already.

I have used I2CBridge from Dimax
(http://www.xdimax.com/u2c/u2c11.html)
I developed i2c slave in firmware(asm) but it's seems to be no
difference in testing.
They have 3 levels of i2c bus commands:
1. Sending complete i2c read/write transactions (including start,
slave address, data and stop as single transaction)
2. Sending separate i2c commands (the same start, stop and data but
which can be sent in separate commands). This is esspecially useful
during implementation of the corresponding blocks.
3. Monitoring and changing i2c bus wires (SCL and SDA). Those commands
helped me to find the bug when my routines didn't released bus.

All of these commands can be sent from GUI application. They also have
library which you can use to build more sophisticated scripts to debug
your module. I used it to prepare stress tests.
