Compile VHDL
Source Dialog Box.

To compile a file from the GUI, the file is selected in the compile dialog

box as shown in Figure 14-4.

The GUI includes a file browser that allows the designer to select the

files to compile and then click the Compile button to compile the file.

To compile a file from the command line interface, the following command

is issued:

vcom cpu_lib.vhd

This checks that the VHDL syntax is correct and converts the VHDL

syntax to the binary format needed to simulate the design. Following is a

complete script that compiles all of the files in the proper order:

vcom cpu_lib.vhd

vcom alu.vhd

vcom comp.vhd

vcom reg.vhd

vcom shift.vhd

vcom control.vhd
