Hey everyone, I'm making a robot which I'm going to program with VHDL. The robot will use the Ping))) sensor from Altera for detecting objects and evade them. When I want to compile my program I get the next errors: 

 

Error (10028): Can't resolve multiple constant drivers for net "pulssensor" at Robosensor.vhd(44) 

Error (10029): Constant driver at Robosensor.vhd(56) 

Error: Can't elaborate top-level user hierarchy 

 

The program that I've written is attached. 

 

Thanks for your help!
Robosensor.vhd

Probably you mistyped the names at lines 62 and 68 and you are supposed to assign pulssensor_int instead of pulssensor. 

The latter is already assigned out of process: you get the compile error because you try to assign it twice.
