*	cxxrtl: emit debug information for constant wires.	whitequark	2020-06-08	1	-5/+6
\| \| \| \| \| \| \| \| \|	Constant wires can represent a significant chunk of the design in generic designs or after optimization. Emitting them in VCD files significantly improves usability because gtkwave removes all traces that are not present in the VCD file after reload, and iterative development suffers if switching a varying signal to a constant disrupts the workflow.
*	cxxrtl: add a C API for driving and introspecting designs.	whitequark	2020-06-06	1	-0/+151
	Compared to the C++ API, the C API currently has two limitations: 1. Memories cannot be updated in a race-free way. 2. Black boxes cannot be implemented in C.
