New Features

- ISE 11.2 software support
- 2-lane product support
- New input pin fast_train_simulation_only to decrease simulation time

Resolved Issues

CR 493708 - Transitioning from D0 to D3hot and back caused the core transmitter to lock-up
Issue resolved where transitioning the Endpoint from D0 to D3hot and back to D0 caused the core transmitter to lock-up.
Fixed in v1.10.1 and included in v1.11.

CR 478312 - GUI Settings to control GTX attributes do not match GTX spec
Issue resolved where the GUI settings to control GTX attributes did not match the GTX specification.

CR 504873 - Endpoint transmitter may lock-up when link partner advertises non-infinite Completion credits
Link partner advertisement of Finite Completion Credits such that the Endpoint is Data credit limited could cause the Endpoint transmitter to lock-up.
Fixed in v1.10.1 and included in v1.11.

CR 509028, 506462 - Completion Streaming can cause Endpoint Receiver buffer Overflow
Packet type switching when in Completion Streaming mode may cause the Endpoint Receiver buffer to Overflow.
Fixed in v1.10.1 and included in v1.11.

CR 436916 - Per-Vector Masking bit Set in MSI Control Register
Issue resolved where the Per-Vector Masking bit in the MSI Control Register was set, though Per Vector Masking is not supported.
Fixed in v1.10.1 and included in v1.11.

CR 513886 - Endpoint Block Plus does not work in asynchronous mode
Issue resolved where the Endpoint Block Plus core did not work when the reference clock between the PC/Motherboard and the Endpoint were different.

CR 518971 - PIO design causing BitGen DRC failures
Issue resolved where dangling block RAM CASCADE Inputs in the PIO design were causing BitGen DRC failures.
