*** NEW June 11, 2021. BrianHG_DDR3_Controller V1.6 ***
*****************************************************
----------------------------------------------------------------
:scared: A maddening over fnK lines of code.... :scared:
----------------------------------------------------------------
My Github has the full latest v1.6 release package:
https://github.com/BrianHGinc/BrianHG-DDR3-Controller
https://github.com/BrianHGinc/BrianHG-DDR3-Controller/archive/refs/tags/v1.60.zip
-----------------------------------------------------
BrianHG_DDR3_Controller V1.6 Release, June 11, 2022.
Includes new BrianHG_GFX_VGA_Window_System.
-----------------------------------------------------
(Control ports are the same as v1.5)
Folder BrianHG_DDR3 now contains the new v1.6 controller.
Main source files:
--- Code: --- - BrianHG_DDR3_v15_and_v16_Block_Diagram.png -> Illustration of module connections.
- Includes these following sub-modules :
- BrianHG_DDR3_CONTROLLER_v16_top.sv -> v1.6 TOP entry to the complete project which wires the DDR3_COMMANDER_v16 to the DDR3_PHY_SEQ giving you access to all the read/write ports + access to the DDR3 IO pins.
- BrianHG_DDR3_COMMANDER_v16.sv -> v1.6 High FMAX speed multi-port read and write requests and cache, commands the BrianHG_DDR3_PHY_SEQ.sv sequencer.
- BrianHG_DDR3_CMD_SEQUENCER_v16.sv -> v1.6 Takes in the read and write requests, generates a stream of DDR3 commands to execute the read and writes.
- BrianHG_DDR3_PHY_SEQ_v16.sv -> v1.6 DDR3 PHY sequencer. (If you want just a compact DDR3 controller, skip the DDR3_CONTROLLER_top & DDR3_COMMANDER and just use this module alone.)
- BrianHG_DDR3_PLL.sv -> Generates the system clocks. (*** Currently Altera/Intel only ***)
- BrianHG_DDR3_GEN_tCK.sv -> Generates all the tCK count clock cycles for the DDR3_PHY_SEQ so that the DDR3 clock cycle requirements are met.
- BrianHG_DDR3_FIFOs.sv -> Serial shifting logic FIFOs.
- Includes the following test-benches :
- BrianHG_DDR3_CONTROLLER_v16_top_tb.sv -> Test the entire 'BrianHG_DDR3_CONTROLLER_v16_top.sv' system with Mircon's DDR3 Verilog model.
- BrianHG_DDR3_COMMANDER_v16_tb.sv -> Test just the commander_v16. The 'DDR3_PHY_SEQ' is dummy simulated. (*** This one will simulate on any vendor's ModelSim ***)
- BrianHG_DDR3_CMD_SEQUENCER_v16_tb.sv -> Test just the DDR3 command sequencer. (*** This one will simulate on any vendor's ModelSim ***)
- BrianHG_DDR3_PHY_SEQ_v16_tb.sv -> Test just the DDR3 PHY sequencer with Mircon's DDR3 Verilog model providing logged DDR3 command results with any access violations listed.
- BrianHG_DDR3_PLL_tb.sv -> Test just the PLL module.
- IO port vendor specific modules :
- BrianHG_DDR3_IO_PORT_ALTERA.sv -> Physical DDR IO pin driver specifically for Altera/Intel Cyclone III/IV/V and MAX10.
- Modelsim 'do' script files.
- All setup_xxx.do files setup their associated Modelsim simulation.
- All run_xxx.do files quick re-compile and run their associated Modelsim simulation.
Folder 'BrianHG_DDR3_GFX_source_v16' contains my new BrianHG_GFX_VGA_Window_System multi-window system.
Main source files:
- BrianHG_GFX_VGA_Window_System.pdf -> Visual block diagram for the graphics system and layer-swapping illustration.
- BrianHG_GFX_VGA_Window_System.txt -> Full documentation for the VGA window system.
- Includes these top hierarchy files:
- BrianHG_GFX_VGA_Window_System.sv -> Full window system where you drive the CMD_win_xxx controls via input ports.
- BrianHG_GFX_VGA_Window_System_DDR3_REGS.sv -> Full window system where you drive the CMD_win_xxx controls via writing to DDR3 memory addresses through any multiport.
- Modelsim 'do' script files.
- All setup_xxx.do files setup their associated Modelsim simulation.
- All run_xxx.do files quick re-compile and run their associated Modelsim simulation.
New Arrow DECA board demo complete projects running the v1.6 BrianHG_DDR3_Controller conected to
the BrianHG_GFX_VGA_Window_System, all at 400MHz, all 100% timing requirements met.
Source folders:
- BrianHG_DDR3_DECA_GFX_DEMO_v16_1_LAYER -> Replaces the original ellipse demo, but now uses my new BrianHG_GFX_VGA_Window_System.
- BrianHG_DDR3_DECA_GFX_DEMO_v16_2_LAYERS -> Improved ellipse demo using 2 translucent windows scrolling at different speeds.
- BrianHG_DDR3_DECA_GFX_HWREGS_v16_16_LAYERS -> Example 16 window layer system where writes to the DDR3 controls the window's regs.
- BrianHG_DDR3_DECA_RS232_DEBUG_TEST_v16 -> Single port DDR3 controller example connected to my RS232 debugger.
- BrianHG_DDR3_DECA_PHY_SEQ_only_v16 -> (No multiport controller.) Bare minimum DDR3 PHY_SEQ controller connected to my RS232 debugger.
Test hypothetical builds for Cyclone III,IV,V to see if we can meet FMAX.
- BrianHG_DDR3_CIII_GFX_TEST_v16_1_LAYER_Q13.0sp1 -> Cyclone III example using Quartus 13.0 sp1.
- BrianHG_DDR3_CIV_GFX_TEST_v16_1_LAYER -> Cyclone IV example using Quartus 20.1.
- BrianHG_DDR3_CV_GFX_TEST_v16_1_LAYER_350MHz -> Cyclone V example running only at 350MHz using Quartus 20.1.

- User 'davemuscle' created an Avalon interface wrapper comparing my DDR3 PHY_SEQ_only free controller to Altera's expensive UniPHY IP, see here:
https://www.eevblog.com/forum/fpga/brianhg_ddr3_controller-open-source-ddr3-controller/msg4108963/#msg4108963
(Note that both controllers should have achieve double the bandwidth and my 'BrianHG_DDR3_DECA_GFX_DEMO_v16_2_LAYERS' demo already runs at double the efficiency.)
- User 'Nockieboy' has been working on integrating my controller with his Z80 8-bit GPU project, see his first multi-layer-window test here:

Nice work. Is there a way to use it with VHDL under Quartus?
BrianHG:
Though I am not familiar with VHDL, I do know that in either Verilog or VHDL, you can initiate either code type module.
Just google: How do I instantiate a SystemVerilog module inside a VHDL design?
There has got to be good examples. You just need to find out how to pass 2 dimentional arrays if you will be using my multi-port module unless you make a simple smaller verilog module with only the ports and settings you want shrinking what you call in your VHDL code.
If crossing code is vendor specific, maybe the best place to ask would be on Intel's forum.
I know Intel has instructions on how to insert VHDL code/modules into verilog source code.

Coming in a few days once I fix the FMAX bottleneck.
