Universal emulation configurator defines trace and measurement tasks
14.00
With the help of this special tool for definition of trace and measurement tasks for on-chip emulation logic, the full potential of the emulation devices can be used without any limitations for troubleshooting and software quality assurance.
The MPC57xx and SPC57x emulation devices are pin-compatible to their respective production chips, but include additional emulation memory, extensive trigger and filter logic as well as connections for a serial high-speed interface based on the Aurora protocol. The Universal Emulation Configurator (UEC) is based on a three-stage programming model which allows developers to configure the additional emulation memory’s hundreds of registers. The assembler-like Trace Qualification Language (TQL) of the first stage uses the resources of the emulation hardware. In this way, the individual register values can be set. The C-like High-Level Trace Qualification Language (HTQL) of the second stage already allows a more abstract description of measurement tasks by conditional actions and definitions of state machines. The third stage of abstraction and the actual user interface is formed by a graphical editor, which allows engineers to put together a measurement task from predefined blocks.
Specific states in the target are described by signals. These, in turn, can initiate actions or shift an underlying state machine into a new state. The individual blocks, which serve to describe signals, actions and basic elements of state machines, are in turn grouped together in libraries. These can be extended as required or supplemented with own libraries. For optimum modularity, the tool uses the Extensible Markup Language (XML), and all analysis tasks from the library can be saved in XML format for later reuse.
