I would really like to advice you to use the latest SPARK GPL toolset and the SPARK book https://www.amazon.co.uk/Building-High-Integrity-Applications-Spark/dp/1107656842/ref=sr_1_1?ie=UTF8&qid=1475489273&sr=8-1&keywords=high+integrity+applications The new SPARK language and toolset are major improvements over the old ones.
