name characters


The characters A to Z, a to z, 0 to 9, slash (/), dash (-), and underscore (_) are legal for Quartus® II breakpoint, chip, clique, directory, file, group (bus), node, parameter, pin, pinstub, and quoted and unquoted symbolic names, with the exceptions listed below.

Item Name Character Exception
file name No slash (/) is permitted. Case is significant on UNIX and Linux workstations; all file names should be in lowercase letters. Case is also significant in Verilog HDL files.
single-range group (bus) name No slash (/) is permitted; the bus identifier cannot end with a digit. The name is followed by a range of numbers or arithmetic expressions in brackets. The start and end of the range are separated by two periods. For example, group a[3..1] consists of the nodes a3, a2, and a1. In Block Editor files only, sequential bus names can also include a series of single-range bus names. For example, a[8..0],dout[6..4].
dual-range group (bus) name Same as single-range group names, with two ranges of numbers or arithmetic expressions in brackets. For example, a[6..3][4..0].
sequential group (bus) name The name consists of a series of comma-separated node names enclosed in parentheses. For example, group (a, b, c) consists of the nodes a, b, and c. In Block Editor files, parentheses are not used.
unquoted symbolic name (AHDL) No dash (-) is permitted. Names cannot consist entirely of digits. AHDL keywords cannot be used.
Verilog HDL identifiers No slash (/) or dash (-) is permitted. Dollar signs ($) are permitted. Names cannot begin with a digit or $. Case is significant. Verilog HDL keywords cannot be used.
VHDL names No slash (/) or dash (-) is permitted. The name must start with a letter, cannot end with an underscore (_), and cannot contain two underscores (_ _) in a row. VHDL keywords cannot be used.
