Description
Reads VHDL source files. This command is similar to the add_files
command. The VHDL files are added to the source fileset as the file is read. If the -library
argument is specified, the file is added with the Library property defined.
You can use this command to read the contents of source files into the in-memory design, when running the Vivado® tool in Non Project mode, in which there is no project file to maintain and manage the various project source files. Refer to the Vivado Design Suite User Guide: Design Flows Overview (UG892) for more information on Non Project mode.
Arguments
-library <arg>
- (Optional) The library the VHDL file should reference. The default VHDL library is xil_defaultlib
.
-vhdl2008
- (Optional) Identifies the files to be read as VHDL file version 2008.
-quiet
- (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
-verbose
- (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config
command.
<files>
- (Required) Names of one or more VHDL files to be read.
Examples
The following example reads the specified VHDL file and adds it to the source fileset:
read_vhdl C:/Data/FPGA_Design/new_module.vhdl
This example reads multiple specified VHDL 2008 files:
read_vhdl -vhdl2008 {file1.vhd file2.vhd file3.vhd}
