Whats the gist of the license/maintenance policy?
Licensing for the FIR HDL Writer works similar to licensing in the EDA (Electronic Design Automation) industry. Licences for the FIR HDL Writer are perpetual for a single user for a single version. All licenses include 1 year of annual maintenace and support with free upgrades for a year after purchase. Maintenance may be renewed after a year on a subscription basis.
