| | 2 | |
| | 3 | To use the debugger simulator, you have to make a few small changes in your SystemC platform : |
| | 4 | |
| | 5 | == 1. The simulation loop == |
| | 6 | |
| | 7 | Just replace the simulation loop at the end of your top cell by calling the function ''debug()'' |
| | 8 | |
| | 9 | before : |
| | 10 | |
| | 11 | {{{ |
| | 12 | sc_start(0); |
| | 13 | for (int i = 0; i < ncycles ; i++) |
| | 14 | { |
| | 15 | sc_start(1); |
| | 16 | |
| | 17 | /* ... */ |
| | 18 | } |
| | 19 | |
| | 20 | /* ... */ |
| | 21 | |
| | 22 | return EXIT_SUCCESS; |
| | 23 | }}} |
| | 24 | |
| | 25 | after : |
| | 26 | |
| | 27 | {{{ |
| | 28 | sc_start(0); |
| | 29 | |
| | 30 | debug(); |
| | 31 | return EXIT_SUCCESS; |
| | 32 | }}} |
| | 33 | |
| | 34 | == 2. Naming the signals == |
| | 35 | |
| | 36 | You'll have to name all the signals inside your design to be able to recognize them when debugging. Otherwise the simulator will rename them with generic names (signal_0, signal_1 ...) |
| | 37 | |
| | 38 | You have two methods to do it : |
| | 39 | |
| | 40 | * name them in the constructor, as you would naturally do in SystemC |
| | 41 | |
| | 42 | * use the function ''rename()'' |
| | 43 | |
| | 44 | The function rename() is used especially for renaming signals declared as n-dimensional array of signals, which you can't do in standard SystemC. |
| | 45 | |
| | 46 | Here's an example of haw to do both methods |
| | 47 | |
| | 48 | {{{ |
| | 49 | /*******************/ |
| | 50 | /* The Constructor */ |
| | 51 | /*******************/ |
| | 52 | |
| | 53 | SC_HAS_PROCESS(MY_COMPONENT); |
| | 54 | |
| | 55 | MY_COMPONENT (sc_module_name insname): |
| | 56 | clk("Clock"), // the standard way of naming signals |
| | 57 | reset("Reset") |
| | 58 | |
| | 59 | { |
| | 60 | #ifdef NONAME_RENAME |
| | 61 | // clk.rename("Clock"); // you can use function rename to name simple signals instead of doing it the standard way |
| | 62 | // reset.rename("Reset"); |
| | 63 | |
| | 64 | char newname[100]; |
| | 65 | |
| | 66 | for (int i=0; i<tab_size; i++ ) |
| | 67 | { |
| | 68 | sprintf(newname, "Tab_Signal_%2.2d", i); |
| | 69 | tab_signal[i].rename(newname); |
| | 70 | } |
| | 71 | #endif |
| | 72 | |
| | 73 | SC_METHOD (my_method); |
| | 74 | sensitive << clk.pos(); |
| | 75 | |
| | 76 | /* ... */ |
| | 77 | |
| | 78 | } |
| | 79 | |
| | 80 | }}} |
| | 81 | |
| | 82 | |
| | 83 | Note the use of ''#ifdef NONAME_RENAME'' to keep the compatibility of your code with SystemC/OSCI |
| | 84 | |
| | 85 | == 3. The Makefile == |
| | 86 | |
| | 87 | Some flags need to be added to compile the simulator |
| | 88 | |
| | 89 | * for Compilation Flags, add ''-I${SOCVIEW}/include'' |
| | 90 | * for Linker Flags, add ''-lreadline -lhistory'' |
| | 91 | |
| | 92 | Now to compile your design, replace the ${SYSTEMC} by the path to the SOCVIEW simulator. |
