From 296f5219da6a2927e84fb748f7f74018c0c1f32e Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Fri, 15 Feb 2019 07:58:05 -0800 Subject: [PATCH] systemc: Export the sc_core::sc_time class to python. This class isn't incredibly useful in python, but it's needed to call some other functions which are more useful.
