sudo apt update
sudo apt install sbt

vscode 安装“Scala (Metals)”扩展，将官方的示例放到 vscode 里，然后等右下角弹框，选 sbt，下一个选 import build，等待完成，然后打开 hw/spinal/projectname/MyTopLevel.scala，“object MyTopLevelVerilog extends App”上面会出现“run | debug”，点击 run，就会在 hw/gen 下生成 .v 文件

生成波形文件和查看波形

sudo apt install zlib1g-dev
sudo apt install verilator gtkwave

这也会生成 .v 文件，在 tmp/job_1 里，如果测试代码完整可以直接走这步
打开 hw/spinal/projectname/MyTopLevelSim.scala，“object MyTopLevelSim extends App”上面也会出现“run | debug”，点击 run，就会在 simWorkspace/MyTopLevel 下生成 .fst 波形文件，可以使用 gtkwave simWorkspace/MyTopLevel/*.fst 直接打开查看波形

vivado

安装选项选择 vivado，vivado ml enterprise，其他默认，等待下载安装完成，默认安装到 /tools/Xilinx

如果无法使用 jtag 调试器，就需要升级 linux 内核，先 apt update & apt upgrade -y 升级一次，如果不行就使用测试通道。

测试通道：包名是 linux-image-amd64。使用“apt search linux-image-amd64”查看仓库里的版本，但是版本不一定够，可以修改“/etc/apt/sources.list”文件里的系统代号为“testing”并apt update，再apt install linux-image-amd64，然后重启，查看内核版本，弄好了就可以把“/etc/apt/sources.list”文件内容还原。

安装:

二选一
.bin 在线安装器直接安装chmod a+x ./Xilinx_Unified_2023.1_0507_1903_Lin64.binsudo ./Xilinx_Unified_2023.1_0507_1903_Lin64.bin.tar...，在线安装器下载压缩包解压安装tar -xvf Xilinx...tar...cd Xilinx...sudo ./xsetup

安装调试器 .rules file:

cd /tools/Xilinx/Vivado/2023.1/data/xicom/cable_drivers/lin64/install_script/install_drivers
sudo ./install_drivers

启动:
默认安装到 /tools/Xilinx/。由于是 sudo 安装，桌面图标在 /root/Desktop/ 下，需要 sudo cp /root/Desktop/* /usr/share/applications/
命令行启动：/tools/Xilinx/Vivado/2023.1/bin/vivado
或桌面图标启动

报错及问题

从命令行启动才能看到报错信息

报错/tools/Xilinx/Vivado/2023.1/bin/rdiArgs.sh: 行 37: 警告：setlocale: LC_ALL: 无法改变区域设置 (en_US.UTF-8)：没有那个文件或目录.../bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)...
解决方法sudo localedef -i en_US -f UTF-8 en_US.UTF-8报错或点击 vivado 图标无法启动application-specific initialization failed: couldn't load file "librdi_commontasks.so": libtinfo.so.5: cannot open shared object file: No such file or directory..
解决方法sudo ln /usr/lib/x86_64-linux-gnu/libtinfo.so.6 /usr/lib/x86_64-linux-gnu/libtinfo.so.5

一个 led 闪烁的示例（MyTopLevel.scala）

package projectnameimport spinal.core._// Hardware definition
case class MyTopLevel() extends Component {val io = new Bundle {val led = out Bool ()}val counter = Reg(UInt(32 bits))val led = Reg(Bool ())io.led := led// 每秒反转 led// reality 是 frequency_t 枚举类型里的值。仿真用低频 simulation 值，板卡测试用实际频率when(counter <= frequency_t.reality.asBits.asUInt) {counter := counter + 1} otherwise {counter := 0led := !led}
}// 自定义的枚举类型
object frequency_t extends SpinalEnum{val simulation, reality = newElement()defaultEncoding = SpinalEnumEncoding("staticEncoding")(simulation -> 10,reality -> 100000000 // 100M)
}object MyTopLevelVerilog extends App {Config.spinal.generateVerilog(MyTopLevel())
}

其生成的 veriloghdl（MyTopLevel.v）

// Generator : SpinalHDL v1.8.1    git head : 2a7592004363e5b40ec43e1f122ed8641cd8965b

其仿真（MyTopLevelSim.scala）

led 只要输出，所以其他的去掉了

package projectnameimport spinal.core._
import spinal.core.sim._object MyTopLevelSim extends App {Config.sim.compile(MyTopLevel()).doSim { dut =>// Fork a process to generate the reset and the clock on the dutdut.clockDomain.forkStimulus(period = 10)for (idx <- 0 to 99) { // 仿真运行 100 个时钟// Wait a rising edge on the clockdut.clockDomain.waitRisingEdge()}}
}
