xPC, getsignalid returns 0, NOT empty
显示 更早的评论
I tried to get signal id by using getsignalid(tg,'signal_name').
For one of the signal in my model, it returns 0 (not empty). I think if the 'signal_name' is wrong, it returns empty. Then, what 0 means? If there is any document about this, I would be happy to know.
Thanks!

I am not presently able to find any information proving that a signal ID _cannot_ be 0. But there is a lot of documentation to go through and it might have been somewhere I did not look yet.

Hi Kosuke,
0 is a valid signal ID and you are correct, [] is returned when the signal name is incorrect.
For example, when you build and download one of our example models "xpcosc", you can execute the following commands to obtain a complete list of signals along with their associated ids:
*tg=xpc
tg.showsignals='on'*
Signals = INDEX VALUE BLOCK NAME LABEL
0 0.000000 Gain
1 0.000000 Gain1
2 0.000000 Gain2
3 0.000000 Integrator
4 0.000000 Integrator1
5 0.000000 Signal Generator
6 0.000000 Sum
Hope that helps,
Shiva
