VCD file dumper

1. specify output file:
+
+ 0> set hw vcd[0] file "name.vcd"
+
+ 2. add locations to dump (sorry, I didn't remember correctly, bits can not + be dumped yet):
+
+ 0> set hw vcd[0] add pc_odr
+ 0> set hw vcd[0] add rom[0x500a]
+
+ You can set the name of the module if you want (set hw vcd[0] module + name), it will be
+ ucsim_vcd_0 by default.
+
+ 3. start recording:
+
+ 0> set hw vcd[0] start
+
+ 4. run the program

5. you can suspend/resume recording:
+
+ 0> set hw vcd[0] pause
+ 0> set hw vcd[0] restart
+
+ You can create an additional recorder with "set hw vcd[0] new id" and + setup it with "set
+ hw vcd[id] ..." commands ("id" must be a number).
+
+ 6. stop recording and close the vcd file:
+
+ 0> set hw vcd[0] stop
+
+ After "stop", you have to specify a new file, because "start" overwrites + the old one!
+
+ For examine, I use gtkwave on linux.
