Where is documentation to the sources file of cusp (cusp-engine-tests.jar\src\... ).

Altera_Forumi don't think its public, what are you trying to do?
- Altera_Forum
It's not documented for a reason..... hint you don't want to be poking around in there.
- Altera_Forum
Because CusP is a better tool than SoPC and Qsys.
- Altera_Forum
how did you arrive at that conclusion? if you look around the forum you'll find that cusp isn't supported and that Altera is porting cusp IP to HDL
- Altera_Forum
CusP and SOPC Builder/Qsys have different purposes so it's a bit odd to even compare them. CusP is only on the ACDS for legacy reasons, it is not being maintained so I wouldn't recommend using it.

But Quartus recognizes CusP component and compiles.

CusP component is working, I tested on DE0 Nano.
example: cusp_test4.c # include <alt_cusp.h> SC_MODULE(cusp_test4) { ALT_GPO<sc_bv<8>> led; void behaviour() { int state = 0; while(1) { for (state = 0; state <= 0xfff; state++) { if (state == 0x1fff) { led.write(1); } else if (state == 0x3ff) { led.write(2); } else if (state == 0x5ff) { led.write(4); } else if (state == 0x7ff) { led.write(8); } else if (state == 0x9ff) { led.write(16); } else if (state == 0xbff) { led.write(32); } else if (state == 0xdff) { led.write(64); } else if (state == 0xfff) { led.write(128); } } } } SC_CTOR(cusp_test4) { SC_THREAD(behaviour); }; }; - Altera_Forum
Use at your own risk then (no support, documentation, etc..) It's typically not a good idea to rely on unsupported features especially when the vendor is moving away from those same features.
- Altera_Forum
Documentation is not needed, I compiled a new "CusP (no_lic)", everything is in the "cusp-engine-tests.jar". Altera make the mistake of not doing support for "CusP".
- Altera_Forum
Full circle to my first post, there is a reason why it's not documented or supported.... It was experimental and wasn't persuded any further. I wouldn't recommend using for production since who knows how long it'll work for (or if it will even remain in the tools).
