labview-fpga-hdl-tools 0.2.2

LabVIEW FPGA HDL Tools

Pre-release LabVIEW FPGA HDL Tools for use with the ni/flexrio repository.

Getting Started

Read the architecture/workflow background in Theory of Operation.

From a target folder that contains projectsettings.ini (for example, c:/dev/github8/flexrio-custom/targets/pxie-7986custom), install dependencies:

pip install -r requirements.txt

All nihdl commands are run from the target folder unless noted otherwise.

nihdl --help

Command Reference

The current CLI surface is defined in labview_fpga_hdl_tools/main.py.

Command	Purpose	Options
migrate-clip	Migrate CLIP assets into top-level HDL workflow artifacts.	--config
install-target	Install generated LabVIEW FPGA target plugin files.	--config
get-window	Extract TheWindow netlist/support files from a Vivado Project Export.	--test, --config
gen-target	Generate full LabVIEW FPGA target support outputs (XML, VHDL stubs, plugin content).	--config
gen-hdl	Generate Window VHDL outputs only.	--config
gen-xdc	Generate XDC files from constraint templates/macros.	--config
create-project	Create or update the Vivado project from INI + file lists.	--overwrite (-o), --update (-u), --test, --config
check-syntax	Run Vivado RTL elaboration syntax/hierarchy check.	--test, --config
compile-project	Run Vivado compile flow to bitstream generation.	--test, --config
launch-vivado	Launch the configured Vivado project.	--test, --config
install-deps	Install GitHub dependencies from dependencies.toml.	--delete, --pre, --latest
create-lvbitx	Build a .lvbitx from Vivado implementation output.	--test, --config
gen-guid	Generate a new GUID for LVTargetGUID.	(none)

Common Command Notes

• Most commands support --config to use an INI path other than ./projectsettings.ini.
• --test validates inputs/settings and skips external tool execution.
• install-deps and gen-guid do not read projectsettings.ini.
• install-deps treats a pre-release specifier in dependencies.toml (for example, ~=26.2.0.dev0) as opting that dependency into pre-release matching even without global --pre.
• create-lvbitx is intended to run from VivadoProject/.runs/impl_1 (it warns if run elsewhere).

Per-Command INI Requirements

Command	Required INI keys (normal run)	Notes
migrate-clip	CLIPMigrationSettings.CLIPXML, CLIPMigrationSettings.LVTargetBoardIO, CLIPMigrationSettings.CLIPHDLTop, CLIPMigrationSettings.CLIPInstantiationExample, CLIPMigrationSettings.CLIPtoWindowSignalDefinitions	If CLIPMigrationSettings.CLIPXDCIn is provided, CLIPMigrationSettings.CLIPInstancePath and CLIPMigrationSettings.CLIPXDCOutFolder are also required.
install-target	LVFPGATargetSettings.LVTargetInstallFolder, LVFPGATargetSettings.LVTargetName, LVFPGATargetSettings.LVTargetPluginFolder	LVTargetInstallFolder and LVTargetPluginFolder must exist.
get-window	LVWindowNetlistSettings.VivadoProjectExportXPR, LVWindowNetlistSettings.TheWindowFolder, VivadoProjectSettings.VivadoToolsPath	In --test mode, Vivado is not launched; path-length enforcement for VivadoProjectExportXPR parent folder is skipped.
gen-target	GeneralSettings.TargetFamily, GeneralSettings.BaseTarget, LVFPGATargetSettings.WindowVhdlTemplates, LVFPGATargetSettings.WindowVhdlOutputFolder, LVFPGATargetSettings.LVTargetPluginFolder, LVFPGATargetSettings.LVTargetName, LVFPGATargetSettings.LVTargetGUID, LVFPGATargetSettings.BoardIOXML, LVFPGATargetSettings.ClockXML, LVFPGATargetSettings.BoardIOSignalAssignmentsExample, LVFPGATargetSettings.TargetXMLTemplates, VivadoProjectSettings.VivadoProjectFilesLists	LVFPGATargetSettings.LVTargetBoardIO is required when IncludeLVTargetBoardIO=True.
gen-hdl	LVFPGATargetSettings.WindowVhdlTemplates, LVFPGATargetSettings.WindowVhdlOutputFolder	LVFPGATargetSettings.LVTargetBoardIO is required when IncludeLVTargetBoardIO=True.
gen-xdc	None enforced by a dedicated validator	For useful output, set VivadoProjectSettings.ConstraintsTemplates. VivadoProjectSettings.TheWindowFolder is used when extracting LV constraints/macros; VivadoProjectSettings.CustomConstraintsFile is optional.
create-project	VivadoProjectSettings.VivadoProjectName, VivadoProjectSettings.TopLevelEntity, VivadoProjectSettings.FPGAPart, VivadoProjectSettings.VivadoProjectFilesLists	Non-test adds VivadoProjectSettings.VivadoToolsPath. If UseGeneratedLVWindowFiles=True, VivadoProjectSettings.TheWindowFolder is required. VivadoProjectSettings.VivadoTclScriptsFolder and template TCL files are also required at runtime.
check-syntax	VivadoProjectSettings.VivadoProjectName, VivadoProjectSettings.TopLevelEntity, VivadoProjectSettings.FPGAPart, VivadoProjectSettings.VivadoTclScriptsFolder	Requires CheckSyntaxTemplate.tcl in VivadoTclScriptsFolder. Non-test adds VivadoProjectSettings.VivadoToolsPath and existing VivadoProject/.xpr.
compile-project	VivadoProjectSettings.VivadoProjectName, VivadoProjectSettings.VivadoTclScriptsFolder	Requires CompileProjectTemplate.tcl in VivadoTclScriptsFolder. Non-test adds VivadoProjectSettings.VivadoToolsPath and existing VivadoProject/.xpr.
launch-vivado	VivadoProjectSettings.VivadoToolsPath, VivadoProjectSettings.VivadoProjectName	Also requires existing VivadoProject/.xpr.
create-lvbitx	GeneralSettings.LabVIEWPath	Uses VivadoProjectSettings.TopLevelEntity to derive input/output filenames. If UseGeneratedLVWindowFiles=True, VivadoProjectSettings.TheWindowFolder is used; otherwise VivadoProjectSettings.CodeGenerationResultsStub is used.
install-deps	None	Command uses dependencies.toml and does not read projectsettings.ini. A pre-release specifier such as ~=26.2.0.dev0 automatically enables pre-release matching for that dependency; --pre enables it globally.
gen-guid	None	Command does not read projectsettings.ini.

projectsettings.ini Reference

Configuration is loaded by common.load_config with these rules:

• Default INI path: ./projectsettings.ini (current working directory).
• Inline comments are stripped after # and ; before parsing.
• Relative paths are resolved from the current working directory.
