A1.5i/F1.5i MAP/HITOP - application error: <program.exe> the instruction at 0x780017## referenced at memory 0x########. The memory could not be written (msvcrt.dll)

Description

Keywords: msvcrt.dll, 0x78001799, 0x5f45434d, 0x780017a7,
0x00000008, map.exe, Hitop.exe, Microsoft Visual
Studio, application error

Urgency: HOT

General Description:

During implementation of an FPGA, the following error may occur
during Map:

Application Error
map.exe the instruction at 0x78001799 referenced memory at
0x5f45434d. The memory could not be written

During implementation of a CPLD a similar error may occur during
hitop:

Hitop.exe the instruction at 0x780017a7 referenced memory at
0x00000008. The memory could not be written

Selecting the debug button that is presented with this error message
will reference a problem with the MSVCRT.DLL file. A similar error
message may occur with other Xilinx applications.

The general cause of this error is due to an inconsistency between
the MSVCRT.DLL file installed by Microsoft Visual Studio 6.0 and
Xilinx's core executables (namely MAP/HITOP).

Although it was first assesed that this problem would be
corrected by the release of the following Microsoft Service Pack:

http://msdn.microsoft.com/vstudio/sp/

it has since been determined that this does NOT fix the problem
from a Xilinx standpoint (althought the Service Pack is still
recommended for the Microsoft Visual Studio 6.0 product).


A fix for this problem is now available with Xilinx Software Version 1.5i Service Pack 2.
This can be found at:

http://www.xilinx.com/support/techsup/sw_updates/

by selecting the appropriate package A1.5i or F1.5i.

Even after the previously mentioned patch has been installed on top of M1.5isp1,
a side affect of the Microsoft Visual Studio tools having been installed is that the
following applications may ALSO produce a Dr. Watson Error, however w/o the
effects of any corruption to your design data:

******************************
Floorplanner - when attempting to save data, File->Save, you will get the following:

Dr. Watson for Win NT - An application error has occured and an app error log is being generated:
fnf2mfp.exe, Exception: Access Violation (0xc0000005 Address: 0x78001799).

Selecting OK will allow you to continue onwards. The .fnf and .mfp files are saved properly...so, no
data will be corrupted.
******************************

******************************
Constraints Editor - When attempting to exit the CE, you get the following:

Dr. Watson for Win NT - An application error has occured and an app error log is being generated: constraints_edi.exe

Selecting OK will allow you to continue onwards. The .ucf file seems to be saved properly...so, no data will be corrupted.
******************************

******************************
Timing Analyzer - When attempting to exit the TA, you get the following:

Dr. Watson for Win NT - An application error has occured and an app error log is being generated: timingan.exe

Selecting OK will allow you to continue onwards. The report files seems to be saved properly...so, no data is corrupted.
