This controller contains a speedometer, two odometers (total 242568SN/A and partial distance), the driver of the car, clocks, and the 252568SN/A pulse generator. The pulses are generated by the sensors placed 262568SN/A around one of the wheel shafts. The rate of pulse generation is 272568SN/A determined by the speed of the car. The driver can start the car, 282665Ssaidi@eecs.umich.edu set its speed, reset the partial distance odometer, and stop the 292665Ssaidi@eecs.umich.edu car (which means he will stop the simulation). One of the clocks 302665Ssaidi@eecs.umich.edu is slow and the other is fast. The fast clock represents the real 312568SN/A time. The slow clock is used to control the actions of the 322568SN/A driver. The signals in this program are traced. 332568SN/A 342982Sstever@eecs.umich.edu purpose (in terms of changes to dash7's purpose) -- Positional 352982Sstever@eecs.umich.edu connection method for binding the ports of modules. Example: Let m 362568SN/A be a module with ports p1 and p2. Let m_ptr be a pointer to m, and 372568SN/A let p1_arg and p2_arg be the ports that we want to bind to p1 and 382643Sstever@eecs.umich.edu p2 of m. Then, we can do the binding in one of the following: 392568SN/A 402568SN/A m(p1_arg, p2_arg); or (*m_ptr)(p1_arg, p2_arg); 412568SN/A m.p1(p1_arg); m.p2.bind(p2_arg); or 422568SN/A m_ptr->p1(p1_arg); m->p2.bind(p2_arg); 432568SN/A 442643Sstever@eecs.umich.edu The output of this program is identical to that of dash6 and dash7. 452643Sstever@eecs.umich.edu 464435Ssaidi@eecs.umich.edu Original Author: Ali Dasdan, Synopsys, Inc. 474435Ssaidi@eecs.umich.edu 482643Sstever@eecs.umich.edu *****************************************************************************/ 494435Ssaidi@eecs.umich.edu 504435Ssaidi@eecs.umich.edu/***************************************************************************** 514435Ssaidi@eecs.umich.edu 522643Sstever@eecs.umich.edu MODIFICATION LOG - modifiers, enter your name, affiliation, date and 532643Sstever@eecs.umich.edu changes you are making here. 542643Sstever@eecs.umich.edu 554435Ssaidi@eecs.umich.edu Name, Affiliation, Date: 564435Ssaidi@eecs.umich.edu Description of Modification: 574435Ssaidi@eecs.umich.edu 584435Ssaidi@eecs.umich.edu *****************************************************************************/ 594435Ssaidi@eecs.umich.edu 604435Ssaidi@eecs.umich.edu// $Log: main.cpp,v $ 614435Ssaidi@eecs.umich.edu// Revision 1.2 2011/01/07 01:20:20 acg 622643Sstever@eecs.umich.edu// Andy Goodrich: update for new IEEE 1666. 634432Ssaidi@eecs.umich.edu// 644432Ssaidi@eecs.umich.edu// Revision 1.1.1.1 2006/12/15 20:26:24 acg 652643Sstever@eecs.umich.edu// systemc_tests-2.3 662643Sstever@eecs.umich.edu// 672643Sstever@eecs.umich.edu// Revision 1.5 2006/01/24 21:05:58 acg 682738Sstever@eecs.umich.edu// Andy Goodrich: replacement of deprecated features with their non-deprecated 692643Sstever@eecs.umich.edu// counterparts. 702643Sstever@eecs.umich.edu// 712643Sstever@eecs.umich.edu// Revision 1.4 2006/01/20 00:43:24 acg 722643Sstever@eecs.umich.edu// Andy Goodrich: Changed over to use putenv() instead of setenv() to accommodate old versions of Solaris. 732643Sstever@eecs.umich.edu// 742643Sstever@eecs.umich.edu// Revision 1.3 2006/01/19 00:48:20 acg 752643Sstever@eecs.umich.edu// Andy Goodrich: Changes for the fact signal write checking is enabled. 762643Sstever@eecs.umich.edu// 772643Sstever@eecs.umich.edu// Revision 1.2 2006/01/18 00:23:51 acg 782643Sstever@eecs.umich.edu// Change over from SC_NO_WRITE_CHECK to sc_write_check_enable() call. 792643Sstever@eecs.umich.edu// 802643Sstever@eecs.umich.edu 812643Sstever@eecs.umich.edu#define SC_NO_WRITE_CHECK 822643Sstever@eecs.umich.edu#include "systemc.h" 832643Sstever@eecs.umich.edu#include "const.h" 842643Sstever@eecs.umich.edu#include "driver.h" 852568SN/A#include "pulse.h" 862568SN/A#include "speed.h" 872568SN/A#include "dist.h" 882568SN/A 892643Sstever@eecs.umich.eduint 904432Ssaidi@eecs.umich.edusc_main(int argc, char *argv[]) 914432Ssaidi@eecs.umich.edu{ 924432Ssaidi@eecs.umich.edu // Pulses for the speedometer and odometers, generated by the pulse 934432Ssaidi@eecs.umich.edu // generator. 942568SN/A sc_signal<bool> speed_pulses("speed_pulses");
