AR# 2275: FPGA Express - Error: Undefined macro `ifdef at or near token '`ifdef', VE-0
AR# 2275
FPGA Express - Error: Undefined macro `ifdef at or near token '`ifdef', VE-0
Description
Keywords: Foundation Express, FPGA Express, Verilog, VE-0, `ifdef
Urgency: Standard
General Description: If a Verilog design uses the `ifdef compiler directive, the following error will occur during the Analyze phase:
Error: Undefined macro `ifdef at or near token "`ifdef" (File: C:\myproj\test\ifdef.v Line: 8) (VE-0)
Solution
The `ifdef directive is not supported by versions of FPGA Express up to and including 3.1. This issue has been addressed in FPGA Express 3.2. See (Xilinx Solution 5791) for details.
