Hi,

To read temperature you need ADC i dont know if spartan3 kit has on chip or on board ADC, if it has then input to ADC will be thermister voltage and depending on output of ADC you can do your needy process, and if it doenot have then you need to inrerface ADC with spartan3 kit.

Hope this url may help, this application is developed by me, and used similar things to read temprature.

Just go through this doc and see your related temprature reading application. Design file and source code is also available from ACTEL site
