Job Description

RISC-V International is looking for a Sail Developer to help develop the RISC-V Formal Model codebase. Part of the acceptance criteria for ratification of a RISC-V hardware specification includes the completion of the formal model deliverables for the extension seeking ratification. RISC-V has chosen Sail from the University of Cambridge as its formal modeling language. RISC-V Sail both uses and depends upon the associated tools including the simulator generator.

This role will develop the Sail formal model support for the RISC-V ISA extensions and augment the Sail infrastructure to support formal model development; work with the RISC-V ISA specification document creation so that the formal model is consistently integrated into the specification and in the formal model files. Collaborate with the RISC-V Staff,  with the Task Groups, Development Partners, and Cambridge Sail staff.

The expected salary range will be $12,000 to $15,000 per month based on experience.

Key responsibilities include:

Develop Sail Formal Model code for extensions and upstream to the RISC-V Sail repository

Develop assembly language tests to demonstrate proper Sail implementation of the extension and/or feature as compared to the text of the specification.

Enhance Sail infrastructure (e.g. simulator generator functionality) to support the RISC-V Formal Model

Work with the RISC-V Sail ecosystem including: the RISC-V Sail maintainer, Cambridge Sail staff, RISC-V Architectural Tests efforts, RISC-V Task Groups, and RISC-V Development Partners to develop the RISC-V Sail Formal Model.

Work with the RISC-V Sail repository maintainer to provide priorities and oversight of RISC-V Sail development throughout the ecosystem

Maintain the RISC-V Sail Formal Model community including mailing lists, informational meetings, and developer training

Communicate status to the RISC-V Task Group Chairs and inform the greater RISC-V community of updates as appropriate
