PLS‘ UDE supports COSIDE simulation model for Bosch’s Generic Timer Module

The GTM from Bosch is implemented in a variety of automotive microcontrollers. It allows capturing digital signals from multiple inputs and generating signals at multiple outputs in real time. In addition to a large number of different function blocks for signal acquisition, filtering and generation, the GTM also includes a number of programmable RISC-based multi-channel sequencers (MCS), which can be used to generate almost any output waveform with complex pulse-width modulation (PWM). The eight programming channels of an MCS can operate in parallel, while ensuring synchronous signal generation. For programming the MCS, C compilers are available from various vendors.

COSEDA Technologies’ COSIDE Simulator allows to simulate the virtual prototype of the General Timer IP Module completely and accurately at high speed. The simulation is independent of a specific microcontroller. Using the powerful modeling methods of COSIDE, both the analog and digital environment as well as the controller software can be efficiently modelled. A wide range of internal debugging tools, such as a powerful wave viewer, also allow all internal signals and states to be observed and analyzed at any time. The virtual prototypes created with COSIDE can be delivered to customers as executable specifications or pre-silicon prototypes for software and hardware development.

For convenient debugging and testing of MCS channel programs in particular, the UDE provides COSIDE users with a front-end that offers the same debugging features they are used to from real hardware: Breakpoints, single-stepping and the display of register and memory values. Software development based on the virtual prototype of the GTM offers a whole range of additional advantages: While the number of hardware breakpoints of the GTM hardware implementation is limited to two and there are no software breakpoints at all, the number of breakpoints that can be used on COSEDA’s simulator is, by principle,   unlimited. Furthermore, when a breakpoint is hit, the entire GTM model is stopped, which is similar to freezing time. As a result, this non-invasive debugging has no impact on the system behavior. In addition, the simulation is 100 percent reproducible and the debugging process is significantly simplified.

Finally, using the UDE as a debugger front-end for COSIDE greatly simplifies the transition to the GTM on real hardware. Since the usage of UDE is completely identical for both the simulator and the real hardware, there is no need to change the tool for this step.
