Clifford Wolf 714f7d9cfa Merged axi4_memory.v and picorv32_wrapper.v back into testbench.v 2016-03-02 12:50:52 +01:00
Olof Kindgren cd5d341e89 Add option to load alternative firmware with plusarg 2016-02-18 22:47:58 +01:00
Olof Kindgren 9591ae9f7d Split out verilator-incompatible code to top-level testbench 
Verilator doesn't handle verilog code that deals with time, such
as delayed signals or the repeat task. Clock and reset generation
are therefore moved to a separate file that can be replaced by
a verilator module. VCD generation is also affected by this.
