dinotrace @ waveform viewer

怎麼 Dinotrace 的 widgets 是如此的醜陋,如果你習慣了Debussy/Verdi 的介面,建議還是用 GTKwave 比較好看的多...不過基於研究的出發點,底下我們就針對幾個topics來討論. 1.VCD format:

//定義 create date or modify date
$date
        Mon Jun 15 17:13:54 1998
$end

//定義 VCD Version
$version
        Chronologic Simulation VCS version 4.0.3
$end

//定義 timescale (時間的刻度)
$timescale
        1ns
$end

//定義 Port range && key map
//ex: $var reg       1 !    clk  $end
//代表 signal name (clk), range 1 bit, key value "!"

$scope module benchx $end
$var reg       1 !    clk  $end
$var reg      11 "    count [10:0] $end
$var reg       1 #    toggle_01  $end
$upscope $end

$enddefinitions $end
#0
$dumpvars
x!                            //clk      =x @0 
x#                            //toggle_01=x @0
bxxxxxxxxxxx "                //count    =bxxxxxxxxxxx @0
$end
#5
0!                            //clk      =0 @5 
#10
1!                            //clk      =1 @10
z#
#15
0!
#20
1!
#25
0!
b00000000000 "
0#

//ps: 如果沒有定義,就接續上個定義的data. 

2. widgets : 這邊用 GTK 當sample...

 GtkWidget *window;
 window = gtk_window_new (GTK_WINDOW_TOPLEVEL);       //建立window
 gtk_widget_set_usize (GTK_WIDGET (window), 200, 100);//設定大小
 gtk_window_set_title (GTK_WINDOW (window), "GTK Menu Test");//name
 gtk_signal_connect (GTK_OBJECT (window), "delete_event",
                        (GtkSignalFunc) gtk_main_quit, NULL); //關閉鈕
 ....
 gtk_widget_show (window); //show window

Menu Widget 了解VCD file format and Widgets 之後,其實剩下的就只是GUI interface的建立.如button + event + menu + widgets + VCD file parser 的結合. Refs: VCD file format Waveform_viewer verdi tutorial SpringSoft
