Swtich between synthesis & simulation

See update below

Edit .editor_defines:

• simulation: define SIMULATION 1define CHECKERS_ENABLED 1 define OPEN_SOURCE_ONLY 1define PRELOAD_BRAMS
• synthesis: //define SIMULATION 1 //define CHECKERS_ENABLED 1 //define OPEN_SOURCE_ONLY 1define PRELOAD_BRAMS

Refresh the project and update hierarchy (or rescan)

Update: Not needed anymore with updated VDT plugin - it now calculates closure per-tool and per-top file defines, so .editor_defines is now just for the editor (which branches to parse). No refresh/rescan is required.

Simulation

• Get unisims library - refresh project files otherwise nothing will work

Synthesis

• Add constraints file through Synthesis parameters
• Bitstream Tool parameters - check Force(overwrite)

Current step in try2 branch:

Not yet tested in hardware, started AHCI implementation (currently coded registers and DMA engine, that processes command table/PRD list, Transfers data between clock domains, re-aligns between WORD size granularity, HBA 32-bit data and 64-bit AXI accesses.

Current step in main branch:

Testing basic functionallity of a host.
Trying out pio access.
Fullfilling device-side drivers and monitors via tasks.
Tests are mostly manual, relied on a common sense and waveforms instpection. Still, complatible both with gtx-gpl and unisims/gtx

Going to do afterwards:

Test dma functionallity of the host.
Make cocotb testbench - gtx-gpl only - random payload high-level verification testing purposes.
Create a base of regression tests, containing lower-level tests - both gtx-gpl and unisims/gtx.
Improve an implementation of DMA control module.
Finally decide what to do with a driver and modify application level (actally, write it from scrap) correspodning to driver's interfaces.
