The MaSoCist is an acronym for 'Martins SoC Instancing, Simulation Toolchain'.
It is a VHDL collection and toolchain based on various open source (and some proprietary) utilities to configure, build and maintain system on chip designs with the focus on lean and mean microcontrollers with optimum code density.
It features the following opensource CPU cores by default:
RISC-V (rv32ui compatible) pyrv32 CPU (VHDL edition only)
It includes a simple wishbone bridge for optional wishbone compliant core adaptation. All hardware definitions are maintained in XML source, which generates C headers, VHDL decoders and documentation in one 'go'.
Basic peripheral cores are included, such as SIC (system interrupt controller), UART, SPI, TIMER, etc.
