-This setup provides a very simple script-based "demo setup" that allows to check out the NEORV32 processor on the Terasic Cyclone-V GX Starter Kit board. -It uses the simplified [`neorv32_test_setup_bootloader.vhd`](https://github.com/stnolting/neorv32/blob/master/rtl/test_setups/neorv32_test_setup_bootloader.vhd) top entity, which is a wrapper for the actual processor -top entity that provides a minimalistic interface (clock, reset, UART and 8 LEDs). - -* FPGA Board: :books: [Terasic Cyclone-V GX Starter Kit FPGA Board](https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=167&No=830) -* FPGA: Intel Cyclone-V GX `5CGXFC5C6F27C7N` -* Toolchain: Intel Quartus Prime (tested with Quartus Prime 20.1.0 - Lite Edition) - - -### NEORV32 Configuration - -:information_source: See the top entity [`rtl/test_setups/neorv32_test_setup_bootloader.vhd` ](https://github.com/stnolting/neorv32/blob/master/rtl/test_setups/neorv32_test_setup_bootloader.vhd) for -configuration and entity details and `create_project.tcl` for the according FPGA pin mapping. - -* CPU: `rv32imcu_Zicsr` + 4 `HPM` (hardware performance monitors, 40-bit wide) -* Memory: 16kB instruction memory (internal IMEM), 8kB data memory (internal DMEM), bootloader ROM -* Peripherals: `GPIO`, `MTIME`, `UART0`, `WDT` -* Tested with version [`1.5.9.4`](https://github.com/stnolting/neorv32/blob/master/CHANGELOG.md) -* Clock: 50MHz from on-board oscillator -* Reset: via on-board button "KEY0" -* GPIO output port `gpio_o` (8-bit) connected to the 8 green user LEDs ("LED7" - "LED0") -* UART0 signals `uart0_txd_o` and `uart0_rxd_i` are connected to the on-board provided USB to UART converter - -:warning: The default [`neorv32_test_setup_bootloader.vhd`](https://github.com/stnolting/neorv32/blob/master/rtl/test_setups/neorv32_test_setup_bootloader.vhd) top entity -is configured for a 100MHz input clock. Since the on-board clock generator of the Cyclone-V GX Starter Kit board needs I2C to be programmed, the fixed 50MHz clock on bank 5B, pin R20 is used for this test setup, and the test setup has to be modified accordingly. -This is automatically done by the `create_project.tcl` TCL script, which makes a local copy of the original test setup VHDL file -(in *this* folder) and uses `sed` to configure the `CLOCK_FREQUENCY` generic (in the local copy) for 50MHz. The local copy is then used as actual -top entity. - -### FPGA Utilization - -``` -Logic utilization (in ALMs) 1,442 / 29,080 ( 5 % ) -Total registers 1771 -Total pins 12 / 364 ( 3 % ) -Total virtual pins 0 -Total block memory bits 231,424 / 4,567,040 ( 5 % ) -Total DSP Blocks 0 / 150 ( 0 % ) -Total HSSI RX PCSs 0 / 6 ( 0 % ) -Total HSSI PMA RX Deserializers 0 / 6 ( 0 % ) -Total HSSI TX PCSs 0 / 6 ( 0 % ) -Total HSSI PMA TX Serializers 0 / 6 ( 0 % ) -Total PLLs 0 / 12 ( 0 % ) -Total DLLs 0 / 4 ( 0 % ) -``` - - -## How To Run - -The `create_project.tcl` TCL script in this directory can be used to create a complete Quartus project. -If not already available, this script will create a `work` folder in this directory. - -1. start Quartus (in GUI mode) -2. in the menu line click "View/Utility Windows/Tcl console" to open the Tcl console -3. use the console to navigate to **this** folder: `cd .../setups/quartus/terasic-cyclone-V-gx-starter-kit-test-setup` -4. execute `source create_project.tcl` - this will create and open the actual Quartus project in this folder. Do NOT run the Quartus-supplied tcl setup script, as that will change all assignment names. -5. if a "select family" prompt appears, go to the "Board" tab, select the "Cyclone V GX Starter Kit" board and click OK -6. double click on "Compile Design" in the "Tasks" window. This will synthesize, map and place & route your design and will also generate the actual FPGA bitstream -7. when the process is done open the programmer (for example via "Tools/Programmer") and click "Start" in the programmer window to upload the bitstream to your FPGA -8. use a serial terminal (like :earth_asia: [Tera Term](https://ttssh2.osdn.jp/index.html.en)) to connect to the USB-UART interface using the following configuration: -19200 Baud, 8 data bits, 1 stop bit, no parity bits, no transmission / flow control protocol (raw bytes only), newline on `\r\n` (carriage return & newline) -9. now you can communicate with the bootloader console and upload a new program. Check out the [example programs](https://github.com/stnolting/neorv32/tree/master/sw/example) -and see section "Let's Get It Started" of the :page_facing_up: [NEORV32 data sheet](https://raw.githubusercontent.com/stnolting/neorv32/master/docs/NEORV32.pdf) for further resources.

This tutorial used the iCEBreaker -"MinimalBoot" setup as reference. - -#### 1. Setup a board- and FPGA-specific top entity - -1. Write a new top design unit that instantiates one of the provided processor templates from -[`rtl/processor_templates`](https://github.com/stnolting/neorv32/tree/master/rtl/processor_templates). -This new top unit can be a Verilog or VHDL file. -2. _Optional:_ You can also include FPGA-specific primitives like PLLs or block RAMs (but keep it simple). These components -need to be added to a FPGA-specific library in [`setups/osflow/devices`](https://github.com/stnolting/neorv32/tree/master/setups/osflow/devices). -3. Try to keep the external IO at a minimum even if the targeted FPGA boards provides cool features. Besides of clock and reset -you need to add at least one kind of IO interface like a UART, GPIO or PWM. -4. Give your new top entity file a specific name that includes the board's name and the instantiated processor template. -The name scheme is `neorv32_[board-name]_BoardTop_[template-name].[v/vhd]`. -5. Put this file in `setups/osflow/board_tops`. -6. Take a look at the iCEBreaker MinimalBoot top entity as a reference: -[`setups/osflow/board_tops/neorv32_iCEBreaker_BoardTop_MinimalBoot.vhd`](https://github.com/stnolting/neorv32/blob/master/setups/osflow/board_tops/neorv32_iCEBreaker_BoardTop_MinimalBoot.vhd) - -#### 2. Pin mapping - -1. Add a new constraints file to define the mapping between the your top unit's IO and the FPGA's physical pins. -You can add _all_ of the FPGA's physical pins even though just a subset is used by the new setup. -2. Name the new constraints file according to the board `[board-name].pcf`. -3. Put this file in `setups/osflow/constraints`. -4. Take a look at the iCEBreaker pin mapping as a reference: -[`setups/osflow/constraints/iCEBreaker.pcf`](https://github.com/stnolting/neorv32/blob/master/setups/osflow/constraints/iCEBreaker.pcf) - -#### 3. Adding a board-specific makefile - -1. Add a board-specific makefile to the `setups/osflow/boards` folder. Name the new constraints file according to the board `[board-name].mk`. -2. The makefile contains (at least) one target to build the final bitstream: -```makefile -.PHONY: all - -all: bit - echo "! Built $(IMPL) for $(BOARD)" -``` -3. Take a look at the iCEBreaker pin mapping as a reference: -[` setups/osflow/boards/iCEBreaker.mk`](https://github.com/stnolting/neorv32/blob/master/setups/osflow/boards/iCEBreaker.mk) - -#### 4. Adding a new target to `index.mk` - -1. Add a new conditional section to the boards management makefile `setups/osflow/boards/index.mk`. -2. This board-specific section sets variables that are required to run synthesis, mapping, place & route and bitstream generation: - * `CONSTRAINTS` defines the physical pin mapping file - * `PNRFLAGS` defines the FPGA-specific flags for mapping and place & route - * `IMPL` defines the setup's implementation name -```makefile -ifeq ($(BOARD),iCEBreaker) -$(info Setting constraints and implementation args for BOARD iCEBreaker) - -CONSTRAINTS ?= $(PCF_PATH)/$(BOARD).pcf -PNRFLAGS ?= --up5k --package sg48 --ignore-loops --timing-allow-fail -IMPL ?= neorv32_$(BOARD)_$(ID) - -endif -``` - -#### 5. Adding a new target to the main makefile - -1. As final step add the new setup to the main osflow makefile `setups/osflow/Makefile`. -2. Use the board's name to create a new makefile target. - * The new target should set the final bitstream's name using the `BITSTREAM` variable. - * Alternative _memory_ HDL sources like FPGA-optimized module can be set using the `NEORV32_MEM_SRC` variable. -```makefile -iCEBreaker: - $(eval BITSTREAM ?= neorv32_$(BOARD)_$(DESIGN).bit) - $(eval NEORV32_MEM_SRC ?= devices/ice40/neorv32_imem.ice40up_spram.vhd devices/ice40/neorv32_dmem.ice40up_spram.vhd) - $(MAKE) \ - BITSTREAM="$(BITSTREAM)" \ - NEORV32_MEM_SRC="$(NEORV32_MEM_SRC)" \ - run -``` - -#### 6. _Optional:_ Add the new setup to the automatic "Implementation" github workflow - -If you like you can add the new setup to the automatic build environment of the project. The project's "Implementation" -workflow will generate bitstreams for all configured osflow setups on every repository push. This is used to check for -regressions and also to provide up-to-date bitstreams that can be used right away. - -1.
