Notes from PSWS / TangerineSDR call of 08-09-2021


1. Discussion on Dave's Runmag software - request to increase the resolution by perhaps 10x or 100x. Bill noted that RF interference measurements did not influence the measurements by visual look at the data, but did just barely show an effect when using a very sensitive statistical test. 


2. Discussion on FPGA tools and macro licensing. We are currently stuck with the GbE interface macro requiring a license in order to compile/synthesize the tri-mode-Ethernet Verilog.  Tom requested Scotty and Nathaniel to work on how to do this. There may be a University license program.    [[ HELP! ]]


Tom found 3 open-source Ethernet MACs but they require most or all of the interfaces to be redone. Some do not support RGMII (the eval board uses only RGMII), none support the Avalon interfaces for streaming and NIOS processor control. Custom Verilog would be needed to adapt these to the MAX10 NIOS, DMA, and Ethernet PHY chip.


The FPGA with Ethernet is needed in order to test the receiver module, and ultimately to create the Data Engine.


3. Nathaniel presented a list of proposed speakers, topics, and program duration for the TAPR DCC conference. The list appears good, several folks on the list were not on the call tonight to confirm.
