Abstract

The invention discloses a Scala-based FPGA development platform. The platform comprises a debugging tool, wherein the debugging tool comprises a host debugging program, an on-chip debugging server and an FPGA hardware controller; the FPGA hardware controller is used for outputting the state of an FPGA program and register data at a corresponding breakpoint according to a control signal after a true FPGA circuit is mounted; the host debugging program is used for generating the corresponding control signal according to debugging content and performing display according to the returned state of the FPGA program and the returned register data; and the on-chip debugging server is used for sending the control signal sent by the host debugging program to the FPGA hardware controller and sending the state of the FPGA and the register data output by the FPGA hardware controller to the host debugging program after the true FPGA circuit is mounted. Through the platform, an interactive debugging function which cannot be achieved through an official FPGA tool is achieved.

Description

technical field [0001] The invention relates to the fields of FPGA hardware circuit design, debugging and verification. Specifically, it mainly involves providing rapid development, debugging and verification methods for hardware circuit design based on field programmable gate array (Field Programmable Gate Array, FPGA), so as to improve the efficiency of the entire process of hardware program design and the accuracy of design results. performance, maintainability and scalability. Background technique [0002] With the application of Field Programmable Gate Array (FPGA), hardware engineers can design optimized circuits for specific functions faster, with lower energy consumption and less space than the traditional way of drawing circuit diagrams and engraving circuit boards. . The demand for hardware acceleration in various fields such as machine learning, high-frequency trading, and big data processing is becoming more and more urgent, and the performance improvement of h...
