This paper describes an opensource padframe generator that was developed on the efabless platform for usage with the Open-Source Qflow Digital Synthesis Flow, for digital logic chips in the X-FAB XH018, 180nm process. It is presented by Philipp, who is a software developer with a strong background in security and cryptography. He is currently learning microelectronics.
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
