This controller contains a speedometer, two odometers (total 247404SAli.Saidi@ARM.com and partial distance), the driver of the car, clocks, and the 257404SAli.Saidi@ARM.com pulse generator. The pulses are generated by the sensors placed 267404SAli.Saidi@ARM.com around one of the wheel shafts. The rate of pulse generation is 277404SAli.Saidi@ARM.com determined by the speed of the car. The driver can start the car, 287404SAli.Saidi@ARM.com set its speed, reset the partial distance odometer, and stop the 297404SAli.Saidi@ARM.com car (which means he will stop the simulation). One of the clocks 307404SAli.Saidi@ARM.com is slow and the other is fast. The fast clock represents the real 317404SAli.Saidi@ARM.com time. The slow clock is used to control the actions of the 327404SAli.Saidi@ARM.com driver. The signals in this program are traced. 337404SAli.Saidi@ARM.com 347404SAli.Saidi@ARM.com purpose (in terms of changes to dash4's purpose) -- synchronous 357404SAli.Saidi@ARM.com processes. 367404SAli.Saidi@ARM.com 377404SAli.Saidi@ARM.com Original Author: Ali Dasdan, Synopsys, Inc. 3810037SARM gem5 Developers 397404SAli.Saidi@ARM.com *****************************************************************************/ 4010873Sandreas.sandberg@arm.com 417404SAli.Saidi@ARM.com/***************************************************************************** 4210474Sandreas.hansson@arm.com 4310474Sandreas.hansson@arm.com MODIFICATION LOG - modifiers, enter your name, affiliation, date and 447404SAli.Saidi@ARM.com changes you are making here. 4510037SARM gem5 Developers 4610037SARM gem5 Developers Name, Affiliation, Date: 477404SAli.Saidi@ARM.com Description of Modification: 487728SAli.Saidi@ARM.com 497404SAli.Saidi@ARM.com *****************************************************************************/ 508245Snate@binkert.org 519152Satgutier@umich.edu// $Log: main.cpp,v $ 528245Snate@binkert.org// Revision 1.2 2011/01/07 01:20:20 acg 538245Snate@binkert.org// Andy Goodrich: update for new IEEE 1666. 5410873Sandreas.sandberg@arm.com// 557748SAli.Saidi@ARM.com// Revision 1.1.1.1 2006/12/15 20:26:24 acg 567404SAli.Saidi@ARM.com// systemc_tests-2.3 577404SAli.Saidi@ARM.com// 587404SAli.Saidi@ARM.com// Revision 1.5 2006/01/24 21:05:56 acg 597404SAli.Saidi@ARM.com// Andy Goodrich: replacement of deprecated features with their non-deprecated 6010913Sandreas.sandberg@arm.com// counterparts. 6110717Sandreas.hansson@arm.com// 6210717Sandreas.hansson@arm.com// Revision 1.4 2006/01/20 00:43:24 acg 6310717Sandreas.hansson@arm.com// Andy Goodrich: Changed over to use putenv() instead of setenv() to accommodate old versions of Solaris. 649258SAli.Saidi@ARM.com// 6510621SCurtis.Dunham@arm.com// Revision 1.3 2006/01/19 00:48:20 acg 6610621SCurtis.Dunham@arm.com// Andy Goodrich: Changes for the fact signal write checking is enabled. 6710037SARM gem5 Developers// 6811588SCurtis.Dunham@arm.com// Revision 1.2 2006/01/18 00:23:51 acg 6911588SCurtis.Dunham@arm.com// Change over from SC_NO_WRITE_CHECK to sc_write_check_enable() call. 7011588SCurtis.Dunham@arm.com// 7111588SCurtis.Dunham@arm.com 7210037SARM gem5 Developers#define SC_NO_WRITE_CHECK 737439Sdam.sunwoo@arm.com#include "systemc.h" 747576SAli.Saidi@ARM.com#include "const.h" 7510037SARM gem5 Developers#include "driver.h" 7610037SARM gem5 Developers#include "pulse.h" 7710037SARM gem5 Developers#include "speed.h" 7810717Sandreas.hansson@arm.com#include "dist.h" 7910037SARM gem5 Developers 8010037SARM gem5 Developersint 8110037SARM gem5 Developerssc_main(int argc, char *argv[]) 8210037SARM gem5 Developers{ 8310037SARM gem5 Developers // Pulses for the speedometer and odometers, generated by the pulse 8410037SARM gem5 Developers // generator. 8510037SARM gem5 Developers sc_signal<bool> speed_pulses("speed_pulses");
