23.2 Document Conventions

This document uses the following variables:

• FPGA family libraries are shown as <act_fam>. Substitute the desired FPGA family variable with the device family as needed. For example: vcom -work <vhd_fam> <act_fam>.vhd

• Compiled VHDL libraries are shown as <vhd_fam>. Substitute <vhd_fam> for the desired VHDL family variable as needed. The VHDL language requires that the library names begin with an alpha character.
