Vitra-MIPS Networked Emulator with Trace
High-Speed Emulator, Source Debugger and Real Time Trace for MIPS™-powered embedded systems

Ashling’s VITRA-MIPS EMULATOR is a powerful networked Emulation and Trace system for embedded development based on the MIPS™ RISC cores. VITRA debugging is completely non-intrusive and requires no target system resources. Together with Ashling’s PathFinder source-level debugger, VITRA provides powerful run/stop control of embedded software, supporting both hardware and software breakpoints.

VITRA provides fast code download to the target MIPS™-powered system, and allows control and interrogation of all processor, co-processor and system resources.

All MIPS™ cores with EJTAG Debug Interface (EJTAG 1.5x, 2.0x, 2.5x and 2.6) are supported.

VITRA includes Instruction and Data Trace and Triggering for target systems that incorporate the MIPS™ EJTAG PCTrace or PDTrace extensions. VITRA provides high-speed Ethernet, USB and serial connections to the host PC.

System Specification

Source Debugger
PathFinder is Ashling's C/C++ Source-Level Debugger for MIPS™ core devices, with multiple user-configurable windows, point-and-click, drag-and-drop, hover help and hover data display, splitter windows, menu-bar, button, hot-key and script (macro)-file controls. PathFinder runs on all 32-bit versions of Windows. PathFinder’s Object-Oriented Monitoring and Editing System provides tree-structured “click to expand” access to all memory-areas, register sets, registers and bits of the MIPS™ Core and co-processors with a logical and friendly Win2000-style display. PathFinder is the user Interface for all Ashling products including the Ashling Vitra, Genia and Opella Emulators for MIPS™.

PahFinder provides source-level debugging for MIPS-powered devices, with mouse, command-line, accelerator-key or button-bar controls

RTOS Monitoring
Integrated RTOS Monitoring Window.

Multi-core/Coprocessor support
Full debug support capability for multi-core and coprocessor-assisted MIPS™ systems.

Compiler support
All popular MIPS™ C/C++ compilers are supported, including WRS/Diab Data, GNU, Green Hills Software, ARC-MetaWare and all other ELF/DWARF compliant compilers.

Host
PC with Windows9x/NT/2000/Me/XP. Ethernet, USB and RS232 serial connection to host PC.

Script language
Powerful script language to control, monitor and log all Emulator functions.
