- timing tab
- timpausecnt (clock ticks of dead time)
- trigcnt: triggers over last second
- trigcntsum: total l1accept
- readcntsum: number of events readout total
- msgdelayset: (units: mhz clock ticks) should be 98 or 99 (there is an "off by one" in the epics variable, and what the hsd sees). if too short, trigger decision is made too early, and there isn't enough buffering in hsd (breaks the buffer model)
- headercntof: should always be zero (ben's module). non-zero indicates that too many l1accepts have been sent and we've overwritten the available buffering
- headercntl0: sum of number of headers received by ben's module.
- headerfifor: the watermark for when ben's stuff asserts dead time
- fulltotrig/nfulltotrig: counters to determine the round trip time from sending an event to getting back the full signal (depends on fiber lengths, for example). nfulltotrig is same thing but with opposite logic.
- pgp tab
- loclinkrdy/remlinkrdy should be ready
- tx/rx clk frequencies should be 156.
- txcnt: counts per second of things being send, but only 16 bits so doesn't really display right value
- txcntsum is transitions and l1accepts (only 16 bits so rolls over frequently) (useful for debugging dropped configure-phase-2)
- buffers tab
- freesz: units of rows of adc readout (40samples*2bytes).
- freeevt: number of free events. if they go below thresholds set in config tab: dead time.
- flow tab
- fmask: bit mask of streams remaining to contribute to event
- fcurr: current stream being read
- frdy: bit mask of streams ready to be read
- srdy: downstream slave (byte packer) is ready
- mrdy: b0 is master valid assert, b1 is PGP transmit queue (downstream of byte packer) ready
- rdaddr: current stream cache read pointer
- npend: next buffer to write
- ntrig: next buffer to trigger
- nread: next buffer to read
- pkoflow: overflow count in byte packer
- oflow: current stream cache write pointer
