there are 2 ways on how interaction happens between SV and C  .

1 . Pin based - where one of the  CPU GPO bit is set from C tests  , SV test will be polling for the that GPO bit to go high . once that GPO bit is set , SV tests part will execute . later .At the end of the SV test , it will another GPO bit , for which C test will be polling . 

2 . Blocking statements(Some pattern in memory ) - Polling for some pattern and once that pattern is received , SV test will execute  .
