Chapter 14: Platform Specification Format (PSF)

MSS - Microprocessor Software Specification

An MSS file is supplied by the user as an input to the Library Generator (LibGen). The MSS

file contains directives for customizing libraries, drivers and file systems.

Please see Chapter 19, “Microprocessor Software Specification (MSS),” for more

information.

PAO - Peripheral Analyze Order

A PAO (Peripheral Analyze Order) file contains a list of HDL files that are needed for

synthesis, and defines the analyze order for compilation.

Please see Chapter 17, “Peripheral Analyze Order (PAO),” for more information.

File and IP Naming Rules

File and IP names must be all lower-case. The reason all names are in lower-case is for

consistency across the following:

x OS: UNIX (case-sensitive) vs. Win (case-insensitive)

x HDL: Verilog (case-sensitive) vs. VHDL (case-insensitive)

A lower-case naming convention is used to deal with the above combinations. For

example, MYCORE_v2_1_0 and mycore_v2_1_0 would mean two different files in UNIX,

whereas in Windows, they would be the same. Or, two different cores depending on VHDL

or Verilog.

Assembly of lower-level cores into the top-level are merged by name reference, therefore,

it's important that names match.

Version Scheme

Form of the version level is X.Y.Z

x X - major revision

x Y - minor revision

x Z - patch level

Version Setting for MHS, and MSS

In the body of the MHS, and MSS file, add the following statement:

Format

PARAMETER VERSION = 2.1.0

The version is specified as a literal of the form 2.1.0.

Version Setting for BBD, MPD, and PAO

The version level is concatenated to the basename of the data files. The literal form of the

version level is vX_Y_Z.
