Trigger:
- Hardware external rising edge
- Hardware external falling edge
- Hardware internal positive slope
- Hardware internal negative slope
- Hardware internal positive slope, threshold range
- Hardware internal negative slope, threshold range
- Hardware internal on channel 1
- Hardware internal on channel 2
- Hardware internal on channel 3
- Hardware internal on channel 4
- Hardware enable
- Software
- Software enable
- Delay range
- Trigger alignment when decimation factor is > 1

Datapath:
- ADC offset correction
- ADC gain correction
- Decimation range
- Pre-trigger samples range
- Post-trigger samples range
- Total number of samples range (full memory, overlapping, etc...)
- Number of shots range
- Multi-shot mode, memory arrangement
- Multi-shot mode, number of samples range (up to max dpram size)
- 

ADC core CSR:
* Acq and trig LEDs manual control bits => tested with production test03
- Test data (Write the address counter value instead of ADC data to DDR)
! Manual bitslip of adc data serdes => Cannot be tested as automatic bitslip is generated in hdl
- Offset DAC clear
- FMC clock enable
- FSM start command
- FSM stop command
- FSM unused commands (shouldn't do anything)
! FSM state => cannot test all states (e.g. DECR_SHOT lasts only 1 tick)
- SerDes PLL lock status (use FMC clock enable)
! SerDes sync status, must be 1 => cannot test more
* Trigger config, delay and software trigger registers => see Trigger chapter
* Number of shots => see Datapath chapter
* Trigger position => see Datapath chapter
* Decimation rate => see Datapath chapter
* Pre-trigger samples => see Datapath chapter
* Post-trigger samples => see Datapath chapter
- Samples counter
* Channel N control register (switches) => tested with production test08
- Channel N value register (use pattern from ADC)
* Channel N correction gain and offset registers => see Datapath chapter

Interrupts:
- Interrupt mask
- DMA done interrupt
? DMA error interrupt => how to force a DMA error
- Trigger interrupt
- End of acquisition interrupt
- Multi-interrupt

Time-tags:
- UTC set register
- Coarse set register
- Trigger tag
- Acquisition start tag
- Acquisition stop tag
- Acquisition end tag


Carrier CSR:
* Carrier type => tested in fmc_adc_spec access class
? Carrier PCB revision => how to automate this test?
! FMC mezzanine presence => cannot automated this test
! P2L PLL lock status, must be 1 => cannot test more
! SysClk PLL lock status, must be 1 => cannot test more
! DDR calibration done status, must be 1 => cannot test more
! SPEC LEDs => cannot automated this test
=> carrier specific firmaware parts will be hard to test...
