Portable FPGA project based on the ARM DesignStart bundle with ARM Cortex-M3 processor

Example of the synthesisable system with the ARM Cortex-M3 processor.

What is ARM DesignStart?

Arm DesignStart helps companies to develop innovative custom chips or FPGA designs, with the lowest risk possible and with an accelerated time-to-market. No matter a company’s budget or design expertise, application-specific designs are achievable and accessible.

Advantages:

1. Fully functional ARM processor with CoreSight debugging subsystem developed by ARM
2. Pre-built AHB/APB interconnect and ARM-developed peripheries
3. Portable RTL code for almost any FPGA board
4. Firmware examples

Disadvantages:

1. Processor and CoreSight subsystem RTL obfuscated by ARM
2. System interconnect cannot be changed because the tool used for code generation (Socrat) is not available
3. This ARM source code cannot be used for the commercial usage accordingly with the ARM license agreement

Simulator of the ARM-based system

Universal Simulator is the part of the another repository riscv_vhdl and it already includes ARM processor model.
