SystemVerilog<\/h2>\n\n\n\n

Avec circt <\/a>on peut g\u00e9n\u00e9rer en systemVerilog avec la m\u00e9thode emitSystemVerilogFile() inclue dans le package: <\/p>\n\n\n\n

import circt.stage.ChiselStage\n\n\/\/...\n\nclass MonModule extends Module {\n \/\/...\n}\n\nobject MonModule extends App {\n    ChiselStage.emitSystemVerilogFile( new MonModule(),\n      firtoolOpts = Array(\"-disable-all-randomization\",\n                          \"--lowering-options=disallowLocalVariables\",\n                          \"-strip-debug-info\"))\n\n}<\/code><\/pre>\n\n\n\n
Le fichier g\u00e9n\u00e9r\u00e9 se nommera MonModule.sv<\/code><\/p>\n\n\n\n
Verilog<\/h2>\n\n\n\n
Pour g\u00e9n\u00e9rer du Verilog il faut utiliser l’ancienne m\u00e9thode que l’on trouve dans le package chisel3.<\/p>\n\n\n\n
object MonModule extends App {\n    val filename = \"MonModule.v\"\n    println(\"Generate verilog source for ChisNesPad Module\")\n    val verilog_src = chisel3.emitVerilog(new MonModule)\n    val filepath = os.pwd \/ filename\n    if (os.exists(file)) os.remove(file)\n    os.write(filepath, verilog_src)\n}<\/code><\/pre>\n\n\n\n
Le choix<\/h2>\n\n\n\n
Et l’on peut s’ajouter une option \u00e0 la ligne de commande si l’on veut avoir le choix.<\/p>\n\n\n\n
import circt.stage.ChiselStage\n\n\/\/...\n\nclass MonModule extends Module {\n \/\/...\n}\n\nobject MonModule extends App {\n  if (args.length == 0) {\n  } else if (args(0) == \"--systemVerilog\") {\n    ChiselStage.emitSystemVerilogFile( new MonModule(),\n      firtoolOpts = Array(\"-disable-all-randomization\",\n                          \"--lowering-options=disallowLocalVariables\",\n                          \"-strip-debug-info\"))\n  }\n}<\/code><\/pre>\n\n\n\n
On lancera les commandes suivantes pour g\u00e9n\u00e9rer l’un ou l’autre :<\/p>\n\n\n\n
