Sargantana: An Academic SoC RISC-V Processor in 22nm FDSOI Technology

This paper describes the Sargantana System on chip (SoC), a 64-bit RISC-V single core processor designed by a number of academic institutions and manufactured in 22 nm FDSOI technology: BSC, UPC, UB, UAB, CIC-IPN and IMB-CNM (CSIC). The SoC includes the processor as well as, among other components, a Phase Locked Loop (PLL) operating up to 2 GHz, interfaces to HyperRAM and a Serdes up to 8 Gbps. The processor has demonstrated experimental correct operation at 800 MHz.
