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. */
