Who's let me know what the 'tlm_quantumkeeper' is?


Recommended Posts

The quantum keeper is used to hold the local time of a time domain in loosly-timed models. E.g. in https://git.minres.com/VP/HIFIVE1-VP/src/branch/master/platform/src/sc_main.cpp#L119 the global quantum is set (the amount of time a time domain is allowed to run ahead). In https://git.minres.com/DBT-RISE/DBT-RISE-RISCV/src/branch/develop/incl/sysc/core_complex.h#L112 the local time is updated (within each instruction) and if the quantum is exceeded, the control is returned to the SystemC kernel (line 114).
