With SystemC +V1.x, this worked with replacing sc_cycle with sc_start (and removing the +sc_initialize), however calling sc_start multiple was an undocumented feature +and it doesnt work in V2.0b2 (no clk is generated). +I know that this problem can be solved by creating an own clock generation +module using wait()s and just a single sc_start in sc_main, but IMHO +sometimes it is desirable to do it the way shown above.
