Tx_buffer.v

Hi,
I am looking at the tx_buffer module. From my understanding, that module
does the interlacing of the data to be transmitted (2 I channels and 2 Q
channels). Is that correct?
Also, next to the bus_reset input declaration there is a comment saying
“Used here for the 257 hack to fix the FX2 bug”. Which bug is it talking
about?

Thank you,

Oussama.

It implements the transmit direction part of the FX2/FPGA GPIF
interface. It also demuxes the data to be transmitted and sends it to
the appropriate DACs.

On the FX2, the WR pulse is asserted one clock longer than it should be.
