Synopsys VCS support

[ciroceissler]

If you follow the tutorial, the compilation will crash. The makefile only supports ModelSim AE 10.5c.

The temporary solution:

• if your project don't use vhdl, remove line 8 of file hardcloud/ase/ase_sources.mk
• change the relative path from '../../' to '../' in hardcloud/samples//hw/vlog_files.list

I will modify the files to support the Synopsys VCS simulator.

tks!
