From 055109800c5f65dcabd07c583c96a5fc20f86ce6 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Fri, 15 Feb 2019 08:00:20 -0800 Subject: [PATCH] systemc: Export the tlm::tlm_global_quantum class to python. This way the python code can set up the global quantum without having an sc_main function to do it.
