Hi Roman Could you please recommend a multi-threaded profiler for SC. I tried making use of gprof but with no success. Thank you

True. It means that the updates should be made to sc_fifo.h: template <class T> inline void sc_fifo<T>::read( T& val_ ) { while( num_available() == 0 ) { sc_core::wait( m_data_written_event ); } bool read_success = sc_fifo<T>::nb_read(val_); if( !read_success ) { sc_assert( read_success ); } }

Hi Patrick you can compile with -DSC_FXDIV_WL=128 to increase max precision of the div operation 100 | .3333333333333333333333333333330703796982596627315294238115724045901089311882969923317432403564453125 | 0b000000000.0101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101 101 | .3333333333333333333333333333330703796982596627315294238115724045901089311882969923317432403564453125 | 0b000000000.01010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010 102 | .333333333333333333333333333333267594924564915682882355952893101147527232797074248082935810089111328125 | 0b000000000.010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101 103 | .333333333333333333333333333333267594924564915682882355952893101147527232797074248082935810089111328125 | 0b000000000.0101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010 104 | .33333333333333333333333333333331689873114122892072058898822327528688180819926856202073395252227783203125 | 0b000000000.01010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101 105 | .33333333333333333333333333333331689873114122892072058898822327528688180819926856202073395252227783203125 | 0b000000000.010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010 106 | .3333333333333333333333333333333292246827853072301801472470558188217204520498171405051834881305694580078125 | 0b000000000.0101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101 107 | .3333333333333333333333333333333292246827853072301801472470558188217204520498171405051834881305694580078125 | 0b000000000.01010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010 108 | .333333333333333333333333333333332306170696326807545036811763954705430113012454285126295872032642364501953125 | 0b000000000.010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101 109 | .333333333333333333333333333333332306170696326807545036811763954705430113012454285126295872032642364501953125 | 0b000000000.0101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010 110 | .33333333333333333333333333333333307654267408170188625920294098867635752825311357128157396800816059112548828125 | 0b000000000.01010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101 111 | .33333333333333333333333333333333307654267408170188625920294098867635752825311357128157396800816059112548828125 | 0b000000000.010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010

Thank you for your response Eyck I used configure/make flow as specified in the INSTALL file: ../systemc-2.3.3/configure \ --prefix=path_to_the_install_dir \ --host=x86_64-redhat-linux-gnu \ --build=x86_64-redhat-linux-gnu \ --target=x86_64-redhat-linux-gnu \ --enable-shared=yes \ --enable-debug=yes \ --disable-optimize \ --enable-pthreads=yes \ --with-gnu-ld=yes \ CXXFLAGS="-std=gnu++11" make -j32 make install

Hi Declarations from utils/sc_stop_here.h are required for diy report handler, however in 2.3.3 this header file is not present in the installation path. The workaround is to make it available in your project somehow

The basic idea: calculate hash for the string call sc_trace for the hash value update a translation file which maps hash values and the string contents. Exemplar github project which utilizes this approach: https://github.com/timurkelin/simschd In this project the translation file is written before the simulation starts raw 64-bit hash values: simvision mmap translation applied: simvision mmap is generated automatically and translates string hash (%x=) into string value (-label {}). mmap new -reuse -name schd -radix %x -contents { {%x=0000000000000000 -label { } -bgcolor #000000 -font -*-courier-medium-i-normal--12-* -shape z -textcolor #F8F8FF -linecolor green} {%x=613d30040ed92e78 -label {delay_chain.dly10} -bgcolor #000000 -font -*-courier-medium-i-normal--12-* -shape bus -textcolor #F8F8FF -linecolor green} {%x=d1a020f2dd73715f -label {delay_chain.dly10} -bgcolor #000000 -font -*-courier-medium-i-normal--12-* -shape bus -textcolor #F8F8FF -linecolor green} {%x=69071983ebd1b6d4 -label {delay_chain.dly10} -bgcolor #000000 -font -*-courier-medium-i-normal--12-* -shape bus -textcolor #F8F8FF -linecolor green} {%x=3a5413510c68f021 -label {run_80.exec_80()} -bgcolor #808000 -font -*-courier-medium-i-normal--12-* -shape bus -textcolor #F8F8FF -linecolor green} {%x=55691ef70e86d835 -label {run_60.exec_60()} -bgcolor #8b0000 -font -*-courier-medium-i-normal--12-* -shape bus -textcolor #F8F8FF -linecolor green} {%x=6f9e19f9823cb15c -label {run_40.exec_40()} -bgcolor #4b0082 -font -*-courier-medium-i-normal--12-* -shape bus -textcolor #F8F8FF -linecolor green} } generated gtkwave translation file for the similar appearance 0000000000000000 ?grey0? 613d30040ed92e78 ?grey0?delay_chain.dly10 d1a020f2dd73715f ?grey0?delay_chain.dly10 69071983ebd1b6d4 ?grey0?delay_chain.dly10 3a5413510c68f021 ?OliveDrab?run_80.exec_80() 55691ef70e86d835 ?DarkRed?run_60.exec_60() 6f9e19f9823cb15c ?navy blue?run_40.exec_40()
