While I'm wearing my Valgrind hat, memcheck detects a few issues in the regression tests tlm/bus_dmi systemc/misc/user_guide/chpt4.4 systemc/datatypes/misc/concat/test07 I haven't looked at the first two. For the last one, here is a cut down version that reproduces the first error. #include "systemc.h" #include "valgrind/memcheck.h" void checkout( const sc_unsigned* actual_p, const sc_unsigned* expected_p ) { cout << *actual_p <<" " << *expected_p << endl; cout <<"another line" << endl; } int sc_main(int argc, c

Hi all, In the context of a very large hardware design simulated in SystemC, we faced some issues with the large footprint of our simulator. After deep and long memory profiling we identified a potential large memory optimization by removing the unique names of each sc_object. To assess the footprint saving coming from this optimization, we tweaked the Accellera kernel implementation to remove unique name generation for objects having an automatically generated name (such as signals) and also we removed the check for name uniqueness. The results were good, in the sense that we were abl

Hi all, I am using an LSF module consisting of a gain and integrator blocks only for calculating input and output energy of a simple ELN module. When I try to simulate a long period of time I notice that the physical memory used by the process continues to increase up to the point that the simulation is stopped due to the following exception: Error: (E549) uncaught exception: std::bad_alloc In file: ../../../../src/sysc/kernel/sc_except.cpp:98 In process: sca_implementation_0.cluster_process_0 That is probably due to the fact that there is no more free physical memory on my machine. I
