Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Unreleased

Added

  • Added support for multiple multiplex groups per pad/port. Each pad/port/port_group can now be member of severa mux_groups. This causes the union of all specified groups to be muxable to the pad,port or port_group in question.
  • Add support for multi-ports. Ports now accept the new optional multiple key that allows to specify several port with similar structure without copy-paste-hell
  • Add support for templated names, description and mux_groups to multi-pads/multi-ports using the '{i}' token. This feature simplifies the definition of GPIO ports. Check the example config file for an example on how to use the feature.
  • Add version flag to CLI to print version information
  • Add validation of manifest version. The CLI now prints out an error message if the manifest version is not supported anymore with a help message which version of Padrick supports the out-dated manifest version.
  • Add mini expression language for template tokens.
  • Render assignment macros in systemverilog package to simplify hierarchical assignements of port groups.
  • Add optional format code feature to index templates.
  • RTL generate command now supports supplying file headers to insert into the auto-generated files
  • Auto-generate SystemVerilog header files with struct assignment macros
  • Added optional key default_port to pad_instances of the form "<port_group_name>.<port_name>". This allows to specify a port that should be connected to the pad by default after reset. An error is raised if the specified default_port is not actually connectable to the pad (not in the same mux group).
  • Added new CLI commands to customize internal Mako templates.
  • Add optional user_attr key to padframe specification format. This allows users to tag pads, ports etc. with additional metadata and potentially use it within the custom templates.

Changed

  • Manifest version was increased to 2.
  • Renamed mux_group key to mux_groups which now accepts a list of string instead of a single string.
  • Updated sample config files to be compatible with new manifest format.
  • Switched to reg_interface version 3.1 and updated internal reggen version.

Fixed

  • Fixed bug in toplevel padfram struct generation

0.1.0 - 2021-03-30
