problem in connect not gate in simulink

Hi friends,<<http://www.4shared.com/photo/Hjaud0Pz/1_online.html>> I have simulating a controller that picture's is attached here from paper. but "NOT gate" is not be connect to Relational Operator and Gdc!why?

Probably you are using CMOS NOT gate from Simelectronics components library and you do not have that toolbox on your system.

Try using NOT gate from simulink library.

yes,i using CMOS NOT gate from Simelectronics,because in simulink library only is CMOS NOT gate! how i find that toolbox is on my system? is there NOT gat in toolbox?!

Answer 2

[Sachin Ganjare]

Use 'ver' command to check whether Simelectronics toolbox is installed on your system

MATLAB=> Version 7.11 Simulink=>Version 7.6

Thanks SACHIN,that block was Logical Operator not CMOS NOT gat!!!

Logical NOT not found in Simulink library in matlab 2012.What should i do ? Beacuse CMOS NOT Gate is also not usable.
