Enabling the Waveform Memory Module allows interleaving of the LVDS data to drive a single DAC
core as well as access to any downloaded waveforms. The on-chip waveform memories allow the
DAC cores to be exercised with user programmable waveforms without the need for an external high
speed pattern generator. The memories are physically implemented using four 2k x 64-bit static
RAMs, assigned as two per DAC for ODD and EVEN samples. The memories can be configured to
drive two different waveforms of equal length, up to 16k points each, to be routed to DAC A and DAC
B independently. Alternatively, it is possible to download multiple waveforms, totalling 16k points or
less, to be selected as required. This last configuration takes advantage of the ability to specify the
waveform start address and length.
Data routing within the Waveform Memory Module is determined by three cascaded multiplexers,
mux_[a/b/c]_ctrl[0:2], as illustrated in Figure 13.
