Code Coverage Analysis

Hi,

I am using LPC2368 microcontroller with Keil UV4 IDE and Ulink2 Jtag for development.
I need to perform code coverage analysis for my program. I had seen Code Coverage option in the but when i debug the code this option is disabled.

I had gone through the forums and found out that code coverage is applicable only for Cortex series or during simulation.

I cannot use simulator as i cannot simulate the real time inputs. So i need to debug and find the code coverage.

So please do suggest me how i can perform the code coverage analysis. If not, are there any other integrated tools that are best suited for Keil IDE to perform the test.

Thanks in Advance.
