1. Verification work 20.03.14 Arild Velure

2. Goals As only part of the final functionality has been implemented for this MPW1, the focus for the testing has been to verify the basic functionality of the digital part to see that it is not malfunctioning or hampering the testing of the analog part. A top-down approach has thus been utilized

3. SAMPA Testbench overview AMS RND sysC Physics DDL* Buffer + + filter models Select & compare Config *2010 TPC ALTRO data Test seq. CH*10 4*serial out Instruction serial I/O Finished Partly finished Not started SAMPA verilog code

4. Default MPW1 configuration Pre trigger / Trigger delay = 0 BC1 = data in – fixed pedestal – Fixed pedestal = 0 -> BC1 disabled Tail cancelation filter = disabled – Coeffecients = 0 BC2 moving average = enabled – pre/post samples = 7 (max) Time window = 1021 samples Trigger mode = Continous Number of serial out = all Zero supression threshold = 10

5. Verification work completed pre+post layout + timing Data+header verification of serial output data vs realistic/random input data – All channels inn and out simultaneously – Default configuration with BC2 disabled – Continous and triggered mode – Ran for 20 timewindows ~2sec Instruction serial interface – Write random data, receive acknowledge of same data – Read back of same data Mux output verification

6. Work remaining Verifying filters Verify buffer sizes – Not needed for MPW1 as long as we run serial out at more than 10 times ADC speed – We have 2 master students currently working on making the simulation Adding analogue and ADC model

8. Notes As the data formating was not updated, there are 3 samples that are not recorded at end of each timewindow SAMPA code has been lint’ed to discover and remove many bugs
