Course Overview

The Building a RISC-V CPU Core (LFD111x) course by the Linux Foundation is a hands-on training program designed for individuals with a technical inclination who are interested in hardware design, including aspiring RTL Design Engineers, Embedded Engineers, and Design Verification Engineers. While no formal certification exam is tied directly to LFD111x, the course serves as foundational preparation for the Linux Foundation’s RISC-V Foundational Associate (RVFA) certification, a credential gaining traction in the open hardware community. With over 1,200 members in RISC-V International driving adoption across IoT, automotive, and AI sectors, demand for RISC-V skilled engineers is rising rapidly among semiconductor and embedded systems firms.

This course covers key technologies including the RISC-V RV32I instruction set architecture, Transaction-Level Verilog (TL-Verilog), and the Makerchip online integrated development environment (IDE), which serves as the primary lab platform. Students engage in practical, browser-based labs where they build a complete RISC-V CPU core from the ground up—starting with logic gates, progressing through combinational and sequential logic, and culminating in a fully functional CPU implementation. Using the Makerchip IDE, learners configure and simulate their designs in real time, gaining experience with waveform visualization and debugging tools. A highlight project involves constructing a working RISC-V subset CPU capable of executing real assembly instructions, providing tangible proof of logic design proficiency.

By completing Building a RISC-V CPU Core (LFD111x), learners gain fundamental skills applicable to careers in hardware design and verification, positioning themselves for roles with competitive salaries—entry-level RTL Design Engineers in the U.S. earn between $90,000 and $120,000 annually. The course prepares students for advanced RISC-V credentials like the RVFA, recognized by industry leaders such as RISC-V International and Redwood EDA. Koenig Solutions enhances this learning path with Guaranteed-to-Run batches, official Linux Foundation courseware, and 1-on-1 instructor support, ensuring learners master complex concepts efficiently. Graduates emerge ready to contribute to open-source hardware innovation and pursue advanced work in processor design and embedded systems.

Frequently Asked Questions

Everything you need to know about the LFD111x training course

Is the certification exam included in the Building a RISC-V CPU Core (LFD111x) course, and what is the exam fee?
The Building a RISC-V CPU Core (LFD111x) course by Linux Foundation does not include the certification exam. You must purchase the RISC-V Foundational Associate (RVFA) exam separately for $250. While the course is free to audit, passing the RVFA exam requires a distinct registration fee to validate your technical expertise.
What training formats are available for the Building a RISC-V CPU Core (LFD111x) course, and does Koenig offer Guaranteed-to-Run scheduling?
The Building a RISC-V CPU Core (LFD111x) course is a self-paced, online program hosted on edX. It is provided directly by the Linux Foundation. Koenig Solutions does not offer live instructor-led sessions or Guaranteed-to-Run scheduling for this specific curriculum, as it is designed for independent, self-directed study.
How long is lab access provided for the Building a RISC-V CPU Core (LFD111x) course, and what is the lab environment?
You receive 7 weeks of lab access for the Building a RISC-V CPU Core (LFD111x) course. This utilizes the cloud-based Makerchip IDE, allowing you to build a full RISC-V CPU core via any web browser. You will use Transaction-Level Verilog to implement logic gates without needing local software installations.
What is the rescheduling and cancellation policy for the RVFA certification exam associated with the Building a RISC-V CPU Core (LFD111x) course?
You may reschedule or cancel your RVFA exam if done at least 24 hours before your appointment. Changes within the 24-hour window are prohibited, and no-shows result in a forfeited fee. You have a 12-month window from the date of purchase to schedule and complete your exam.
What is the format, number of questions, passing score, and time limit for the RVFA certification exam related to the Building a RISC-V CPU Core (LFD111x) course?
The RVFA exam is a 90-minute, proctored, multiple-choice assessment. It covers five domains: RISC-V Overview (10%), ISA (35%), Assembly Language (25%), C Programming (15%), and Operating Systems & Tools (15%). While the exact passing score remains confidential, the exam rigorously tests your foundational knowledge of RISC-V architecture.
How long is the RISC-V Foundational Associate (RVFA) certification valid, and what is the renewal process and cost?
Your RVFA certification remains valid for 2 years. To maintain active status, you must retake and pass the current RVFA exam at the standard $250 fee. There are no continuing education credits or renewal discounts available, requiring a full re-examination to keep your certification credentials current.
What post-training support does Koenig provide after completing the Building a RISC-V CPU Core (LFD111x) course?
Koenig does not provide post-training support for the Building a RISC-V CPU Core (LFD111x) course. This program is managed exclusively by the Linux Foundation via edX.
