Failed to launch MegaWizard™ Plug-In Manager. PLL Intel® FPGA IP v18.0 could not be found in the specified library paths
Description In the Quartus® Prime software version 18.0, when you want to open the MegaWizard™ for editing, you may see error message "Failed to launch MegaWizard™ Plug-In Manager. PLL Intel® FPGA IP v18.0 could not be found in the specified library paths". Resolution To work around this problem, 1) Locate the .lst file of the missing IP in your Intel® FPGA program directory. For example, for the missing PLL, locate "pll_wizard.lst". In the case of Windows: Windows <installation_directory> \ip\altera\altera_pll In the case of Linux: Linux <installation_directory>/linux64/ip/altera/altera_pll 2) Change the text. "<ALIAS>Altera® PLL v18.0</ALIAS>" to "<ALIAS>PLL Intel® FPGA IP v18.0</ALIAS>Why does my desktop hang when using the SignalTap II Logic Analyzer?
Description Due to a problem in the Quartus® II software versions 10.0 and later, using the SignalTap™ II Logic Analyzer may cause your desktop to hang or become unresponsive to mouse clicks. Specific actions that can trigger this problem include resizing column widths or zooming in or out on data waveforms. This problem is known to affect 64-bit Windows operating systems, but can potentially impact other platforms.

Description Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 19.1, you may see this internal error when compiling an Intel® Stratix® 10 design containing a PR (Partial Reconfiguration) region. This problem occurs when the static root partition has been migrated from an earlier backward compatible version. Resolution To work around this problem, discard the original compiled static root partition and recompile it in the Intel® Quartus® Prime Pro Edition Software version 18.1 Update 1 or later.cc1plus.exe: out of memory allocating 65536 bytes
Description This error may be seen when compiling large software projects on Windows platforms. cc1plus.exe is a 32bit Windows application and has access to 2GB of memory on Windows. Resolution To work around this problem, Windows can be configured to allow 32bit applications access to a 3GB address space. 1. Enable 3GB address space for 32bit applications on Windows: From Windows command prompt run: bcdedit /set IncreaseUserVa 3072 2. Allow cc1plus.exe to use the larger address space From Windows command prompt run: editbin /LARGEADDRESSAWARE "<path>/cc1plus.exe“ This problem is scheduled to be fixed in a future release of the SoC EDS Software.Why does .jic file programming of EPCQ-A devices fail when multiple Intel® Cyclone® 10 LP devices are in the same JTAG chain?
Description Due to a problem in the Intel® Quartus® Prime Software version 18.1, the programming of EPCQ-A devices is executed incorrectly with JTAG Indirect Configuration (.jic) file. You will see the failure when there are more than three Intel® Cyclone® 10 LP devices in a single JTAG chain, where each is connected to an EPCQ-A device as configuration flash. Resolution This problem was fixed in a recent version of the Intel® Quartus® Prime Software.Critical Warning : Active Serial configuration mode is selected without INIT_DONE pin enabled. Depending on the configuration setup and board design, INIT_DONE pin may need to be enabled in the design.
Description You may get this Critical Warning message, when targetting a Stratix® V, Arria® V or Cyclone® V device and you have not enabled the optional INIT_DONE function in your Quartus® II project. Resolution In Active Serial (AS) multi-device configuration mode, Altera recommends that the INIT_DONE output pin option is enabled in the Quartus II software for devices in the configuration chain. Do not tie INIT_DONE pins together between master and slave devices. Monitor the INIT_DONE status for each device to ensure successful transition into user-mode.Why does the Quartus II programmer display a different flash memory name when performing an Auto Detect when multiple flash memory devices are connected to the parallel flash loader (PFL)?
Description When multiple flash memory devices are connected to the PFL in MAX® devices, the Quartus® II programmer displays a different flash memory name when performing Auto Detect. This is because the programmer functions as follows: (1) First time you press Auto Detect, the programmer will display multiple flash memory devices. (2) Second time you press Auto Detect, the programmer will display a single flash memory device. (3) Third time you press Auto Detect, the programmer will display multiple flash memory devices and ask to confirm to overwrite existing settings. (4) Fourth time you press Auto Detect, the programmer will display a single flash memory device. Thereafter, (3) and (4) are repeated. The first time, the programmer will display multiple flash memory devices according to physical structure. The second time, the programmer will display a single flash memory device according to device database in the software. The programmer treats multiple flash memory devices as a single flash memory device in reality. The programmer will save the existing chain in the Chain Description File (.cdf) when going from a single flash device to multiple flash devices. The programmer can save only the device which exists in the database. The programmer does not ask you to confirm when going from multiple flash memory devices to a single flash memory device. This behavior is expected and never affects flash device programming.Is there any known issue with Stratix® 10 FPGA Configuration via Protocol (CvP) operation in Quartus® Prime Pro Edition Software version 18.1?
Description You may encounter the following failure when trying to perform the Configuration via Protocol (CvP) operation in Quartus® Prime Pro Edition Software version 18.1: When you perform any Configuration via Protocol operation, there is a small chance that the operation will halt. This issue impacts all Stratix® 10 FPGA production devices. During the Configuration via Protocol (CvP) process, if the bitstream is corrupted after the first 168kB of data, the CVP_CONFIG_ERROR bit in the CvP Status Register goes high. This will cause the Stratix® 10 FPGA device to hang, and another Configuration cannot recover it via a Protocol (CvP) update. This issue impacts all Stratix® FPGA 10 production devices. Resolution Power cycle the Stratix® FPGA device to perform the next Configuration via Protocol (CvP) operation.What is the difference between rtpio and rrpio IBIS model designations?
Description The difference between rtpio and rrpio IBIS model designations is as follows : rtpio represents the DIFFIO_TX_p channel for dedicated LVDS I/O pins. rrpio represents the DIFFIO_RX_p channel for dedicated LVDS I/O pins.Why does the Intel® Quartus® Prime Pro Edition software GUI hang after issuing synthesis errors during compilation?
Description Due to a problem in the Intel® Quartus® Prime Pro Edition software versions 19.3 and earlier, the Graphical User Interface (GUI) may hang after issuing synthesis errors during compilation. Resolution A patch is available to fix this problem for the Intel® Quartus® Prime Pro Edition software version 19.3. Download and install Patch 0.20 from the appropriate link below. Download patch 0.20 for Windows (.exe) Download patch 0.20 for Linux (.run) Download the Readme for patch 0.20 (.txt). This problem is fixed beginning with version 19.4 of the Intel® Quartus® Prime Pro Edition software
