Gas Gauge (register) emulator?

Other Parts Discussed in Thread: BQ40Z50, EV2400

I'm working on a smart battery charger tester which should present the charger with a GG register emulator that I can control through a USB I2C bridge (something like an EV2300, EV2400, Aardvark, etc).  The emulator does not have to reproduce the function of the Gas Gauge, but it has to present to the charger the same registers a gas gauge (ex. bq40Z50, bq20Z??) would, and allow me to set its registers from a test program.

Thank you.

    Hi Marius,

    We do not have something we can provide as a software emulator for a gas gauge. Have you considered simply using a real gas gauge device, and having it respond on the bus? It can be connected to a power supply rather than a real battery, so it would be powered and could respond to I2C communication, although the data would not be relevant.

    Thanks,

    Terry

    Using a GG with a PS is option B, we want something more general.  We design multiple packs using different GGs, and don't want to deal with GGs for each application.
