### DCS Verilog Instantiation

Source: https://github.com/yosyshq/apicula/wiki/DCS

Verilog instantiation example for the Gowin DCS primitive, showing how to connect the clock inputs, clock output, and control signals.

```APIDOC
## DCS Primitive

### Description
The Gowin DCS (Dynamic Clock Selector) primitive dynamically switches between four clock inputs (GCLK0-GCLK3) using a CRU. It supports two switching modes: Non-glitchless and Glitchless.

### Ports
- **CLK0** (1-bit input) - Clock input 0
- **CLK1** (1-bit input) - Clock input 1
- **CLK2** (1-bit input) - Clock input 2
- **CLK3** (1-bit input) - Clock input 3
- **CLKOUT** (1-bit output) - Selected clock output
- **CLKSEL** (4-bit input) - Clock select signal
- **SELFORCE** (1-bit input) - Force selection signal

### Parameters
- **DCS_MODE** (default: RISING) - Sets the clock switching mode (e.g., Non-glitchless or Glitchless).

### Verilog Instantiation
```verilog
DCS #(
    .DCS_MODE(DCS_MODE)
) dcs_inst (
    .CLK0(CLK0),
    .CLK1(CLK1),
    .CLK2(CLK2),
    .CLK3(CLK3),
    .CLKOUT(CLKOUT),
    .CLKSEL(CLKSEL),
    .SELFORCE(SELFORCE)
);
```

### Check and add installed binaries to PATH

Source: https://github.com/yosyshq/apicula/blob/master/readme.md

Commands to verify that the installed binaries are on the PATH and to add them if necessary. Running the source files directly will lead to import errors.

```bash
which gowin_pack # check if binaries are on the path
python -m site --user-base # find the site packages base directory
ls $HOME/.local/bin # confirm the binaries are installed in this folder
export PATH="$HOME/.local/bin:$PATH" # add binaries to the path
```

--------------------------------

### Run fuzzers with pip install and make

Source: https://github.com/yosyshq/apicula/blob/master/readme.md

Run the fuzzers and build the ChipDB in a checkout of this repo. Requires Gowin vendor tools version 1.9.10.03 (newer versions may work but are untested) and sets GOWINHOME to the Gowin installation directory.

```bash
pip install -e .
export GOWINHOME=/gowin/installation
make
```

--------------------------------

### Install apycula with pure Python alternatives

Source: https://github.com/yosyshq/apicula/blob/master/readme.md

Use this command on platforms where the default C extension dependencies are not available. It installs apycula without dependencies and adds msgpack and cattrs as pure Python alternatives.

```bash
pip install --no-deps apycula msgpack cattrs
```

### Build blinky for Tangnano9k with family flag

Source: https://github.com/yosyshq/apicula/blob/master/readme.md

For the Tangnano9k board, nextpnr and gowin_pack must be called with the chip family GW1N-9C. The device variable is assumed to be set as in the previous example.

```bash
nextpnr-himbaechel --json blinky.json \
                   --write pnrblinky.json \
                   --device $DEVICE \
                   --vopt family=GW1N-9C \

### Basic Gowin FPGA flow: synthesize, place and route, pack, and program

Source: https://github.com/yosyshq/apicula/wiki/Home

Commands to run the complete open source FPGA development flow for Gowin FPGAs: synthesize Verilog to JSON with Yosys, place and route with nextpnr-himbaechel, generate bitstream with gowin_pack, and program with openFPGALoader. The example uses a Tang Nano 9K board and a GW1NR-LV9QN88PC6/I5 device.

```bash
# 1. Synthesize Verilog to JSON netlist
yosys -p "read_verilog design.v; synth_gowin -json design.json"

# 2. Place and route the design
nextpnr-himbaechel --json design.json --write placed.json \
                   --device GW1NR-LV9QN88PC6/I5 \
                   --vopt cst=constraints.cst

# 3. Generate bitstream
gowin_pack -d GW1N-9C -o final.fs placed.json

# 4. Program the FPGA
openFPGALoader -b tangnano9k final.fs

### Instantiate DP primitive with all parameters and ports

Source: https://github.com/yosyshq/apicula/wiki/DP

Use this Verilog instantiation to connect the DP primitive in your design. All parameters and ports are listed; replace the placeholder signals with your actual nets. The INIT_RAM_00 through INIT_RAM_3F parameters initialize the RAM contents.
