Hello @AmeyaVS I resolved it by increasing the amount of memory mapping allowed by the Linux kernel by setting the parameter vm/max_map_count. The command is sudo sysctl vm/max_map_count=<number> Thanks for your suggestions. Regards, Perrin NT.

Hello @AmeyaVS, All instances are already create within top-level constructor. The top-level module is instantiate using std::make_unique<top>("") statement. They should be stored within the heap. The simulation crashes at the early stage of the simulation. I am suspecting during objects instantiation. Regards

I am trying to simulate an SRAM memory using SystemC and have to allocate several 2D arrays. When I increase the number of bitcells to simulate I got std::dad_alloc error. I am suspecting stack size issue and went through several already opened topics here but couldn't fine the solution Beforre systemC compilation, I also set this SC_DEFAULT_STACK_SIZE_ 0x16000000 variable it helps me increase the array size but not enough as required. sc_vector<sc_vector<bitcell>> memory; sc_vector<sc_vector<sc_signal<sc_logic, SC_MANY_WRITERS>>> bit_value_in; sc_vector<sc_vector<sc_signal<sc_logic, SC_MANY_WRITERS>>> bit_value_out; sc_vector<sc_signal<sc_logic>> periphOutput; sc_vector<sc_signal<sc_logic, SC_MANY_WRITERS>> periphInput1; sc_vector<sc_signal<sc_logic, SC_MANY_WRITERS>> periphInput2; sc_vector<sc_signal<bool, SC_MANY_WRITERS>> periph_enable; sc_vector<sc_vector<sc_signal<bool, SC_MANY_WRITERS>>> wr_enable; sc_vector<sc_vector<sc_signal<bool, SC_MANY_WRITERS>>> rd_enable; For each declared 1D/2D vector I have a creator function to instantiate the objects. The SRAM has 1 bank of 4 arrays each with 128x256 bit-cell size Please can you direct me the parameter to change in order to get rid of this bad_alloc message ? Thanks
