Minutes
Present: Naomi (CMU), Beni, David, Cody, Lubomir, Sergey (JLab)
- Cody has incorporated Naomi's new module into the fa125 firmware and it synthesized successfully, there are a few other issues to sort out but the timing module looked ok, he will try the q>0 test pulses in simulation and then return to working on the architecture.
- Naomi updated the CDC_algo wiki page to be consistent with the new code which Cody has and the C++ code sent to David. This will next be moved into the format document. She is working on producing some illustrative plots. We discussed the error code table a little.
- Cody is still working on the FA250-modified firmware regarding the trigger times. There are limitations on the shortest interval between trigger times in multi-block mode which depend on the data mode and window size, he will try to quantify these, and needs to set up a separate simulator. He asked if we need to record high rate data in raw mode; Beni and David answered yes, one of the goals of the next run period is high-speed writing to tape, aiming for 15kHz with < 50% deadtime.
- The FA250-modified firmware now writes one set of trigger time header words per event, not per FPGA chip.
- The faulty FA125s have been replaced and the CDC now has all 3552 channels working.
- Beni will let us know if he needs anything for the collaboration meeting talk.
