Quartus® II support for Verilog 2001 is described in the following table. Section numbers match those in the IEEE Std. 1364-2001 IEEE Standard Verilog Hardware Description Language manual. Note that the sections numbers do not always match those in the IEEE Std 1364-1995 IEEE Hardware Description Language Based on the Verilog Hardware Description Language manual. This table lists all supported constructs, but lists only the major unsupported constructs.
