Agnisys @ DVCon Europe: Showcasing Test Sequence Generator for RISC-V Cores and SoCs

Munich, Germany – October 21, 2019 – Agnisys, Inc., the leading EDA provider of the industry’s most comprehensive solution for Design and Verification of SoC Hardware/Software Interface (HSI), to showcase a novel test sequence generator for RISC-V cores and SoCs at DVCon Europe in Munich Germany on October 29-30, 2019.

“One of the main challenges in creating test sequences is that the same sequence functionality must be coded by multiple engineers several times in UVM, C or CSV to support various test environments,” said Anupam Bakshi, Founder/CEO. “This aspect of verification can certainly be automated to increase team productivity.”

Employing a golden-spec methodology, ISequenceSpec™ provides the environment for describing test sequences in pseudo-code using Python text, Word™ document or Excel™ spreadsheet. The sequence generator is able to re-target the sequences in various languages such as SystemVerilog UVM for simulation, C/Python for firmware tests and Python/C/ASCII/CSV for board testing.

We cordially invite you to see our demo at Booth #301. The demo is based on SweRV™ core, a 32-bit dual-issue 9-stage pipeline open-source processor, where we described the initialization and regular operation sequences for its on-chip Programmable Interrupt Controller. The auto-generated sequences include the following:

  • UVM Sequence Package for UVM-based Simulation – We create sequence classes that are extended from ‘uvm_reg_sequence’ Arguments are handled here using ‘init´ function. Read/write transactions on registers occurs via register model ‘rm’ inside the task body.
    • uvm.sv – sequence file
    • uvm.sv – package file
  • C Sequence Package for Firmware Tests – We create functions with a particular ‘return type’ that can be changed in the configuration settings. Users can perform register and field writes through the tool default APIs or user APIs.
    • h – header file
    • c – sequence file
    • h – API file
    • h – package file
  • Platform Sequence Package for Board Testing – Users can specify the base address of the IP implemented in the board, APIs used for writing/reading the registers, pre-defined initialization and clean up functions . Once generated, the sequences are ready to run on the board.
    • h – header file
    • c – sequence file

For a more detailed description of the tool flow, see our most recent blog on the subject Creating Test Sequences for RISC-V Cores and SoCs.

The latest release of ISequenceSpec is now available for download and free evaluation.

About ISequenceSpec™
ISequenceSpec provides the environment for capturing the SoC configuration, programming and test sequences in a golden specification. Capture the sequence once in pseudo-code using spreadsheet or text, and generate the required sequences in SystemVerilog for simulation, C/Python for firmware tests, C for emulation and CSV/ASCII for post-silicon validation.  Changes in the golden specification only requires re-generation of the target sequence code. With full access to the register and memory map in SystemRDL, IP-XACT or CSV, users can easily capture test sequences for register read/write and transaction-level messages using advanced constructs including loops, if-else, wait, arguments, constant or in-line functions.
