As usual, December was rich in events for our team. We attended three conferences, one in Russia and two in USA, where we presented MicroTESK in general (core and engines), MicroTESK for RISC-V (tools for test program generation and deductive binary code verification), and RISC-V Architecture Verification Suite, so-called RISC-V AVS (a set of test programs generated mostly by MicroTESK): Ivannikov ISP RAS Open Conference (ISPRAS Open) held in Moscow, Russia on December 5-6, 2019Microprocessor Test and Verification Workshop (MTV) held in Austin, TX, USA on December 9-10, 2019RISC-V Summit held in San Jose, CA, USA on December 9-12, 2019 We are full of plans and looking forward to implementing them next year. Happy 2020!

Our research on binary code deductive verification was presented at the Workshop on Design Automation for Understanding Hardware Designs (DUHDe), a part of the Design Automation and Test in Europe Conference (DATE), held in Florence, Italy on March 29, 2019. In this work, MicroTESK is used to specify a target instruction set architecture (ISA) and to extract the symbolic representation of a given binary file. Other tools in use include Frama-C, Jessie, and Why3. To demonstrate the approach, we utilize RISC-V, a free and open ISA.  

What's New? Specification of address translation (Sv32, Sv39, and Sv48) Demo templates for address translation Test suite based on QEMU4V 0.3.2 MicroTESK for RISC-V 0.0.8 can be downloaded from here.

MicroTESK 2.4.45 has been released New features are as follows: Block-level register allocation constraints; MMU plugin: structures' fields are listed from upper to lower bits. Block-level register allocation constraints This facility is aimed at overriding default settings written in the configuration file. MicroTESK 2.4.45 can be downloaded from here.

MicroTESK framework and machine-readable specifications of the RISC-V ISA were presented at RISC-V Summit held in Santa Clara, CA on December 3-6, 2018 and Workshop on Microprocessor/SoC Test, Security & Verification (MTV) held in Austin, TX on December 10-11, 2018. We reviewed MicroTESK for RISC-V and discussed a couple of its applications: test program generation and binary code verification. RISC-V is a free and open ISA enabling a new era of processor innovation through open standard collaboration. Each year, the RISC-V Foundation hosts global events to bring the expansive ecosystem together to discuss current and prospective RISC-V projects and implementations, as well as collectively drive the future evolution of the ISA forward. This was the first-ever RISC-V Summit with 1000+ registrants from 20 countries around the globe, 29 exhibitors, and…

MicroTESK was presented at the Technology Exhibition of the ISPRAS OPEN Conference held in Moscow on November 22-23, 2018. ISPRAS Open is an annual event organized by Ivannikov Institute for System Programming of the Russian Academy of Sciences (ISPRAS). This year's conference was dedicated to the 70th anniversary of Russian Computer Science. On June 29, 1948, the Council of Ministers of the USSR issued the Decree №2369 on organization of Institute of Precision Mechanics and Computer Engineering (IPM and CE) of the Academy of Sciences of the USSR. On December 4, 1948, Isaak Brook, a corresponding member of the Academy of Sciences of the USSR, and his team received a certificate №10475 for invention of the electronic computing machine. On December 17, 1948, the Council of Ministers of the USSR…

MicroTESK 2.4.44 has been released New features are as follows: support for sections stored in separate files (useful for boot generation); decoder generator improvements: decode attribute and bit selection in image. Sections stored in separate files There are supported sections stored in separate files (an argument :file has been introduced). That facility may be useful for boot generation. Decoder generator A primitive (mode or op) is allowed to specify a decode attribute describing how to construct the primitive's arguments from the temporary variables (this is a hint to the decoder generator). It is permitted to select bits of non-immediate arguments in the primitive's image. MicroTESK 2.4.44 can be downloaded from here.
