Type conversion from hex String to uint (32 bits) in Specman e

bharathwajan

Hi All,

 

I am trying to read a file which has address and data in hex separated by space as shown below :

0001FF 0x47295784

I am having problem with converting the hex string 0001FFF to uint 32 bits and send this to my driver for further action. I have tried the following syntax from the cadence docs:

int = %{string};

int = pack(packing.low,string)

 Neither of them helped. In the both cases, the string is converted to a signed int. The doc doesnt help me convert string to uint (32 bits).

Could you pelase help me? 

Could anyone please help me do this type conversion?  

 Thank you !!! 

 Best Regards,

Bharath. 

  •  Hi,

     what you want is specman to interpret the string as a number. You can do this easily with "<string>".as_a(uint). However you need to consider how specman wants a hex to look like, namely it should be prefixed with "0x". So if you do "append("0x", string).as_a(uint)" you should get what you want. You can try it out on the specman console as well 'print "0xcafecafe".as_a(uint)'.

     

    Hope this helps,

    Daniel

  • Hi Daniel,

     

    Thank a lot. It worked. I had tried this way but i didnot append "ox" to the string. Now it works.

     

    Thanks again !!!

     

    Best Regards,

    Bharath.
