This controller contains a speedometer, two odometers (total + and partial distance), the driver of the car, clocks, and the + pulse generator. The pulses are generated by the sensors placed + around one of the wheel shafts. The rate of pulse generation is + determined by the speed of the car. The driver can start the car, + set its speed, reset the partial distance odometer, and stop the + car (which means he will stop the simulation). One of the clocks + is slow and the other is fast. The fast clock represents the real + time. The slow clock is used to control the actions of the + driver. The signals in this program are traced. + + dash8's purpose (in terms of changes to dash7's purpose) -- + Positional connection method for binding the ports of modules. + Example: Let m be a module with ports p1 and p2. Let m_ptr be a + pointer to m, and let p1_arg and p2_arg be the ports that we want + to bind to p1 and p2 of m. Then, we can do the binding in one of + the following: + + m(p1_arg, p2_arg); or (*m_ptr)(p1_arg, p2_arg); + + m.p1(p1_arg); m.p2.bind(p2_arg); or + m_ptr->p1(p1_arg); m->p2.bind(p2_arg); + + The output of this program is identical to that of dash[6-8]. + + purpose (in terms of changes to dash8's purpose) -- the use of + module and process declaration macros, defined in systemc.h. + + Original Author: Ali Dasdan, Synopsys, Inc. + + *****************************************************************************/ + +/***************************************************************************** + + MODIFICATION LOG - modifiers, enter your name, affiliation, date and + changes you are making here. + + Name, Affiliation, Date: + Description of Modification: + + *****************************************************************************/ + +// $Log: main.cpp,v $ +// Revision 1.2 2011/01/07 01:20:20 acg +// Andy Goodrich: update for new IEEE 1666. +// +// Revision 1.1.1.1 2006/12/15 20:26:24 acg +// systemc_tests-2.3 +// +// Revision 1.5 2006/01/24 21:05:59 acg +// Andy Goodrich: replacement of deprecated features with their non-deprecated +// counterparts. +// +// Revision 1.4 2006/01/20 00:43:24 acg +// Andy Goodrich: Changed over to use putenv() instead of setenv() to accommodate old versions of Solaris. +// +// Revision 1.3 2006/01/19 00:48:20 acg +// Andy Goodrich: Changes for the fact signal write checking is enabled. +// +// Revision 1.2 2006/01/18 00:23:51 acg +// Change over from SC_NO_WRITE_CHECK to sc_write_check_enable() call. +// + +#define SC_NO_WRITE_CHECK +#include "systemc.h" +#include "const.h" +#include "driver.h" +#include "pulse.h" +#include "speed.h" +#include "dist.h" + +int +sc_main(int argc, char *argv[]) +{ + // Pulses for the speedometer and odometers, generated by the pulse + // generator. + sc_signal<bool> speed_pulses("speed_pulses"); + sc_signal<bool> dist_pulses("dist_pulses"); + // Signals for the driver's actions. + sc_signal<bool> reset("reset"); + sc_signal<int> speed("speed"); + sc_signal<bool> start("start"); + + // Signals observed by the driver. + sc_signal<double> disp_speed("disp_speed"); + sc_signal<double> disp_angle("disp_angle"); + sc_signal<double> disp_total_dist("disp_total_dist"); + sc_signal<double> disp_partial_dist("disp_partial_dist"); + + // Clocks. + sc_clock clk0("slow_clk", SLOW_CLOCK_PERIOD0, SC_NS, 0.5, 0.0, SC_NS, true); + sc_clock clk1("fast_clk", FAST_CLOCK_PERIOD1, SC_NS, 0.5, 0.0, SC_NS, false); + + driver_mod driver("driver"); + driver(clk0, disp_speed, disp_angle, disp_total_dist, + disp_partial_dist, reset, speed, start); + + gen_pulse_mod gen_pulse("gen_pulse"); + gen_pulse(clk1, start, speed, speed_pulses, dist_pulses); + + speed_mod speedometer("speedometer"); + speedometer(clk1, start, speed_pulses, disp_speed, disp_angle); + + dist_mod odometers("odometers"); + odometers.pulse(dist_pulses); + odometers.reset(reset); + odometers.start.bind(start); + odometers.total(disp_total_dist); + odometers.partial.bind(disp_partial_dist); + + // Initialize signals: + start = false; + + // Tracing: + // Trace file creation. + sc_trace_file *tf = sc_create_vcd_trace_file("dash"); + // External signals. + sc_trace(tf, clk0, "slow_clk"); + sc_trace(tf, clk1, "fast_clk"); + sc_trace(tf, speed_pulses, "speed_pulses"); + sc_trace(tf, dist_pulses, "dist_pulses"); + sc_trace(tf, reset, "reset"); + sc_trace(tf, start, "start"); + sc_trace(tf, speed, "speed"); + sc_trace(tf, disp_speed, "disp_speed"); + sc_trace(tf, disp_angle, "disp_angle"); + sc_trace(tf, disp_total_dist, "disp_total_dist"); + sc_trace(tf, disp_partial_dist, "disp_partial_dist"); + // Internal signals. + sc_trace(tf, speedometer.elapsed_time, "elapsed_time"); + sc_trace(tf, speedometer.read_mod->raw_speed, "raw_speed"); + sc_trace(tf, speedometer.filtered_speed, "filtered_speed"); + sc_trace(tf, odometers.ok_for_incr, "ok_for_incr"); + sc_trace(tf, odometers.total_dist, "total_dist"); + sc_trace(tf, odometers.partial_dist, "partial_dist"); + + disp_speed = 0.0; + disp_angle = 0.0; + disp_total_dist = 0.0; + disp_partial_dist = 0.0; + + sc_start(); + + return 0; +} + +// End of file diff --git a/src/systemc/tests/systemc/misc/v1.0/dash9/pulse.cpp b/src/systemc/tests/systemc/misc/v1.0/dash9/pulse.cpp new file mode 100644 index 000000000..c2b5031f2 --- /dev/null +++ b/src/systemc/tests/systemc/misc/v1.0/dash9/pulse.cpp @@ -0,0 +1,101 @@ +/***************************************************************************** + + Licensed to Accellera Systems Initiative Inc.
