BSVC: A Microprocessor Simulation Framework

BSVC is a microprocessor simulation framework written in C++ and Tcl/Tk. It was developed as a senior design project at North Carolina State University by Bradford W. Mott (see the Credits.txt file for copyright information).

Since its original development many professors and students have found BSVC to be a useful tool in courses based on the Motorola 68000. It has also been used as a starting point for other senior design projects.

In April 2015, maintenance was restarted by Dan Cross and the system was relicensed under the GNU Public License, version 2.1.

The BSVC distribution contains the following:

  • Motorola 68000 simulator & assembler (Supports the M68681 Dual UART)
  • Motorola 68360 simulator (CPU32 like simulator)
  • Simple devices including the M68681 DUART, a timer, RAM and a GDB interface
  • BSVC Graphical User Interface (written in Tcl/Tk)
  • BSVC Simulator Framework (C++ classes)

Code cross-compiled with GCC is known to load and run.

Supported Systems

The BSVC distribution is known to compile on the following systems:

  • Linux
  • Solaris
  • Mac OS X
  • FreeBSD

Any reasonable POSIX system should work.

Required Software

BSVC requires the following software to compile and run:

  • C++11 and C11 compliant compilers for C++ and C, respectively. Both clang and recent versions of GCC are known to work.
  • GNU Make
  • A recent version of Tcl/Tk

Distribution Site

The BSVC distribution can be downloaded from Github:
