The Universal Emulation Configurator (UEC) from PLS Programmierbare Logik & Systeme is now available for the emulation devices MPC57xx from Freescale and SPC57x from STMicroelectronics. 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.

In order for developers to configure the several hundred registers of the additional emulation memory, the Universal Emulation Configurator (UEC) is based on a three-stage programming model. 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 the abstraction and the actual user interface is formed by a graphical editor, with which a measurement task can be put together from predefined blocks. In doing so, 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.

The Universal Emulation Configurator (UEC) helps the user to cope with the limited resources of the on-chip emulation memory. In parallel to this, the implemented Aurora interface offers the possibility to externally record a very large amount of trace data and to carry out a statistical analysis of the program flow such as code coverage and profiling. PLS’ Universal Access Device 3+ (UAD3+) with Aurora pod serves for recording, while the evaluation itself is carried out by the Universal Debug Engine (UDE).
