to build the shell script for ‘vsdflow’ on CentOS, and finally I have the first cut ready. You just need to follow steps given in below link for CentOS, and all opensource EDA tools (PNR, STA, Layout, LVS) will be installed on your system. There are 2 testcases (picorv32 and spi_slave) inside the below link to test whether all tools have been installed or not. After running the shell script in below link, you need run the testcase
Few months back, I had posted the below floorplan of picoSoC, which is a simple (yet powerful) example of SoC using picoRV32, which can run code directly from SPI flash chip and can be used as a turn-key solution for trivial tasks in ASIC and FPGA designs
This blog is regarding abstract submission for VSDOpen2018, which is the first online conference in VLSI, that covers all aspects of semiconductor technology with prime focus to build SoC using RISC-V CPU by illustrating exciting ways using (only) opensource EDA tools.
Just to give you some background, picoSoC is an example SoC using PicoRV32, and PicoRV32 is a size-optimized RISC-V CPU which implements RV32IMC instruction set architecture.
A high-level program, like swap.c as shown below is first converted to an assembly language program (RISC-V in below example) using compiler. This assembly language is converted to binary machine language program using an assembler. This level of abstraction of your application using high-level programming languages like C, C++, Java or Visual Basic, proves to be a great idea to improve design
