-/* SUBSECTION
- Verilog hex memory file handling
-
- DESCRIPTION
-
- Verilog hex memory files cannot hold anything but addresses
- and data, so that's all that we implement.
-
- The syntax of the text file is described in the IEEE standard
- for Verilog. Briefly, the file contains two types of tokens:
- data and optional addresses. The tokens are separated by
- whitespace and comments. Comments may be single line or
- multiline, using syntax similar to C++. Addresses are
- specified by a leading "at" character (@) and are always
- hexadecimal strings. Data and addresses may contain
- underscore (_) characters.
-
- If no address is specified, the data is assumed to start at
- address 0. Similarly, if data exists before the first
- specified address, then that data is assumed to start at
- address 0.
-
-
- EXAMPLE
- @1000
- 01 ae 3f 45 12
-
- DESCRIPTION
- @1000 specifies the starting address for the memory data.
- The following characters describe the 5 bytes at 0x1000. */
