This controller contains a speedometer, two odometers (total 2412855Sgabeblack@google.com and partial distance), the driver of the car, clocks, and the 2512855Sgabeblack@google.com pulse generator. The pulses are generated by the sensors placed 2612855Sgabeblack@google.com around one of the wheel shafts. The rate of pulse generation is 2712855Sgabeblack@google.com determined by the speed of the car. The driver can start the car, 2812855Sgabeblack@google.com set its speed, reset the partial distance odometer, and stop the 2912855Sgabeblack@google.com car (which means he will stop the simulation). One of the clocks 3012855Sgabeblack@google.com is slow and the other is fast. The fast clock represents the real 3112855Sgabeblack@google.com time. The slow clock is used to control the actions of the 3212855Sgabeblack@google.com driver. The signals in this program are traced. 3312855Sgabeblack@google.com 3412855Sgabeblack@google.com dash8's purpose (in terms of changes to dash7's purpose) -- 3512855Sgabeblack@google.com Positional connection method for binding the ports of modules. 3612855Sgabeblack@google.com Example: Let m be a module with ports p1 and p2. Let m_ptr be a 3712855Sgabeblack@google.com pointer to m, and let p1_arg and p2_arg be the ports that we want 3812855Sgabeblack@google.com to bind to p1 and p2 of m. Then, we can do the binding in one of 3912855Sgabeblack@google.com the following: 4012855Sgabeblack@google.com 4112855Sgabeblack@google.com m(p1_arg, p2_arg); or (*m_ptr)(p1_arg, p2_arg); 4212855Sgabeblack@google.com 4312855Sgabeblack@google.com m.p1(p1_arg); m.p2.bind(p2_arg); or 4412855Sgabeblack@google.com m_ptr->p1(p1_arg); m->p2.bind(p2_arg); 4512855Sgabeblack@google.com 4612855Sgabeblack@google.com The output of this program is identical to that of dash[6-8]. 4712855Sgabeblack@google.com 4812855Sgabeblack@google.com purpose (in terms of changes to dash8's purpose) -- the use of 4912855Sgabeblack@google.com module and process declaration macros, defined in systemc.h. 5012855Sgabeblack@google.com 5112855Sgabeblack@google.com Original Author: Ali Dasdan, Synopsys, Inc. 5212855Sgabeblack@google.com 5312855Sgabeblack@google.com *****************************************************************************/ 5412855Sgabeblack@google.com 5512855Sgabeblack@google.com/***************************************************************************** 5612855Sgabeblack@google.com 5712855Sgabeblack@google.com MODIFICATION LOG - modifiers, enter your name, affiliation, date and 5812855Sgabeblack@google.com changes you are making here. 5912855Sgabeblack@google.com 6012855Sgabeblack@google.com Name, Affiliation, Date: 6112855Sgabeblack@google.com Description of Modification: 6212855Sgabeblack@google.com 6312855Sgabeblack@google.com *****************************************************************************/ 6412855Sgabeblack@google.com 6512855Sgabeblack@google.com// $Log: main.cpp,v $ 6612855Sgabeblack@google.com// Revision 1.2 2011/01/07 01:20:20 acg 6712855Sgabeblack@google.com// Andy Goodrich: update for new IEEE 1666. 6812855Sgabeblack@google.com// 6912855Sgabeblack@google.com// Revision 1.1.1.1 2006/12/15 20:26:24 acg 7012855Sgabeblack@google.com// systemc_tests-2.3 7112855Sgabeblack@google.com// 7212855Sgabeblack@google.com// Revision 1.5 2006/01/24 21:05:59 acg 7312855Sgabeblack@google.com// Andy Goodrich: replacement of deprecated features with their non-deprecated 7412855Sgabeblack@google.com// counterparts. 7512855Sgabeblack@google.com// 7612855Sgabeblack@google.com// Revision 1.4 2006/01/20 00:43:24 acg 7712855Sgabeblack@google.com// Andy Goodrich: Changed over to use putenv() instead of setenv() to accommodate old versions of Solaris. 7812855Sgabeblack@google.com// 7912855Sgabeblack@google.com// Revision 1.3 2006/01/19 00:48:20 acg 8012855Sgabeblack@google.com// Andy Goodrich: Changes for the fact signal write checking is enabled. 8112855Sgabeblack@google.com// 8212855Sgabeblack@google.com// Revision 1.2 2006/01/18 00:23:51 acg 8312855Sgabeblack@google.com// Change over from SC_NO_WRITE_CHECK to sc_write_check_enable() call. 8412855Sgabeblack@google.com// 8512855Sgabeblack@google.com 8612855Sgabeblack@google.com#define SC_NO_WRITE_CHECK 8712855Sgabeblack@google.com#include "systemc.h" 8812855Sgabeblack@google.com#include "const.h" 8912855Sgabeblack@google.com#include "driver.h" 9012855Sgabeblack@google.com#include "pulse.h" 9112855Sgabeblack@google.com#include "speed.h" 9212855Sgabeblack@google.com#include "dist.h" 9312855Sgabeblack@google.com 9412855Sgabeblack@google.comint 9512855Sgabeblack@google.comsc_main(int argc, char *argv[]) 9612855Sgabeblack@google.com{ 9712855Sgabeblack@google.com // Pulses for the speedometer and odometers, generated by the pulse 9812855Sgabeblack@google.com // generator. 9912855Sgabeblack@google.com sc_signal<bool> speed_pulses("speed_pulses");
