| Pull: | #1197 (7 additions, 7 deletions, 1 files changed) |
| Branch: | slaclab/saci_6_chip |
Notes:
Description
The
AxiLiteSaciMastercurrently has a fixed limit of four ASICs ("chips"). This has been increased to six to work with a new readout system with that many ASICs.Details
The new 3x2 Readout (https://confluence.slac.stanford.edu/x/eKRxG) seems to be first system to use more than four ASICs with a common SACI interfaces. There is no mention why only four chips were allowed previously. The hardware will arrive in a couple of weeks with which we can test running SACI with six chips, but from the code alone I don't see any reason why more than four would not work.

| Branch: | slaclab/RstSync-std_logic |
Notes:
Description
- Using "std_logic" instead of "sl" for generics due to issues with SystemVerilog handling VHDL subtype on generics properly

| Branch: | slaclab/pgp4lite-rstPolarity |
Notes:
introduce rst_polarity feature to all pgp4txlite/pgp4rx modules to prepare for asic deployment
(ASIC designs usually employ an active-LOW reset/i.e. a rstN/enable signal)
add RST_POLARITY_G to all modules.
note that I also added RST_POLARITY_G to RX-related modules because I use them in my local behavioral simulation (no receiver in ASICs are foreseen). Since the RST_POLARITY_G generic default values are consistent, the changes in the TX/RX modules hopefully should not have impact on existing designs.
