Request to support SiLabs' EFM32PG28 & PG28-PK2506A

[sch0bert]

Description

I would like to request the support for the latest SiLabs EFM32PG28 as it includes new features that could benefit the community to try, ej AI/ML module and Arm Cortex-M33 core

The development board is the PG28-PK2506A

Usage example

Simulate the core and dev board.

Additional information

Dev Board datasheet: https://no.mouser.com/datasheet/2/368/ug545_efm32pg28_brd2506a_user_guide-3314819.pdf

Do you plan to address this issue and file a PR?

I tried to create the repl file based on the efm32g210.repl file but I don't know if the support of this microcontroller is part of the latest Renode version (1.15.0) as this file contains references such as "I2C.EFM32GGI2CController" where it points to the EFM32G family. Also, I don't know if there is such a "EFM32PG" family that can replace the reference "EFM32G" in the deviceInformation section.

Hi @sch0bert , thanks for asking the question.

As you've already mentioned Renode has support for many Silicon Labs platforms from different families.
Reusing peripheral models between them is a common pattern - in fact this is how the devices are built internally as well.
As long as registers layout and logic fits it's safe to mix them - in Renode they implement abstract interfaces which make them compatible with each other.

Right now we do not have EFM32xG2 series, but it seems that some peripherals are similar to EFR32BG27 which we support in our Zephyr Dashboard and Renodepedia.

That could be a good starting point for building a more complex simulation. The SoC you're working with might reuse part of those blocks or require models that differ just a bit.

The M33 CPU core itself is supported, see:

renode/platforms/cpus/stm32l552.repl

Line 7 in 5bae845

cpuType: "cortex-m33"

for an example.

Please remember that we accept contributions as well as provide commercial support in modeling of platforms.
