I got underflows when trying to run them myself...

artiq.coredevice.exceptions.RTIOUnderflow: RTIO underflow at 36465748268 mu, channel 5

@pca006132 Did you correctly load the nist_qc2 gateware and firmware variant? The ARTIQ tests do not work with the simple variant.

Note that the impure build process doesn't handle changing variants without deleting the build folder manually.

The underflows could be due simply to the very high Zynq AXI latency. I'll take a look.

Hmm, no. Then my best guess is DMA buffer corruption similar to #90
