Verilog Include Paths and Defines
Old Content - visit altium.com/documentation
Altium Designer 14.3 sees enhanced support for Verilog, with improvements to the way in which include paths are defined at the project-level. In addition, the ability to specify global macro definitions (Defines) is also facilitated through project options. Controls are available in the Verilog Include Paths and Defines region, on the Options tab of the Project Options dialog (Project » Project Options).
Specify Include Paths and Defines for use with your Verilog-based FPGA designs.
Example use of Include files in a Verilog source file. The files are found along the path specified in the project's options (previous image).
