Readme file for Quartus II 12.0 SP2 Patch 2.dp2
Copyright (C) Altera Corporation 2012 All right reserved.
Patch created on August 17 2012
Patch case#: 70292
//****************************************************************

Please note, this patch is meant to address known software issues for
Stratix V, Arria V and Cyclone V devices in the Quartus II software
version 12.0 SP2.

The device patches are cumulative.

======================================
The following were addressed in 2.dp2:
======================================
--------------------
Issue 1 (case 65815)
--------------------
This patch allows designs to see the association between the DSP
enable signal and the input registers for Arria V devices.


--------------------
Issue 2 (case 66224)
--------------------
This patch enables POF support for Stratix V F4 devices.


--------------------
Issue 3 (case 66618)
--------------------
If an Arria V GX parts has both datarate larger than 3125Mbps and
smaller than 3125Mbps, the transceiver voltage is 1.1V for datarate
smaller than 3125Mbps and 1.15V for datarate larger than 3125Mbps.
This resulted a clash of voltages on VCCR/VCCT when using datarate
above and below 3125Mbps.


--------------------
Issue 4 (case 67678)
--------------------
This patch updates Stratix V OCT calibration block settings in 
Quartus II software to match changes in Rref resistance from 2 KOhm
to 1.8 KOhm. New settings also applies to Stratix V GT channels.

Instructions: User must regenerate Quartus II Software IP files and
recompile his/her design for this patch to take effect:

1.On a Qsys-based design, by opening the design in Qsys,
  (re)generating the files and recompiling.

2.On a Megawizard-based design, by opening the existing Megawizard
  design, (re)generating the files and recompiling.


--------------------
Issue 5 (case 69027)
--------------------
This patch enables POF support for Arria V 500GT/GX devices.


--------------------
Issue 6 (case 69480)
--------------------
The Fitter may not consistently promote all clock edges in a clock
domain to use dedicated clock routing, if any of its destination
registers are used to generate additional clock or control signals.

This patch addresses this issue, and should reduce clock skew on the
affected clock domain(s).

The following INI is required to enable this change:
fsv_adjust_clock_promotion_behavior=on


--------------------
Issue 7 (case 69534)
--------------------
Quartus II triggers the following Internal Error in Fitter stage:

Internal Error: Sub-system: FSV, 
File: /quartus/fitter/fsv/fsv_module_mint_dq_grouping.cpp 
Line: 1179
(*group_query).second == id


--------------------
Issue 8 (case 69608)
--------------------
This patch enables POF support for Stratix V 5SGXEB5R2F43I3 device



Caution - You must either have previously installed the
          Quartus II 12.0 SP2 software or must
          install the Quartus II 12.0 SP2 software
          before installing this patch. Otherwise, the patch will
          not be installed correctly and the Quartus II
          software will not run properly.
