Abstract
A method and apparatus is provided to significantly increase the flexibility of readback capture mechanisms, the apparatus being an integrated circuit device, comprising a configuration data router coupled to receive at least one configuration data frame from a configuration interface, a configuration memory space coupled to the configuration data router and adapted to receive the configuration data frame to define a user logic block and a capture block within the programmable logic device, the user logic block including, a monitor control block coupled to the capture block and adapted to report activity within the user logic block to the capture block, and a configuration control logic block coupled to the capture block that is adapted to assert the capture signal in response to the asserted alert signal.
