Why does my Quartus® Prime Installation fail with certificate error: SSL certificate problem: unable to get local issuer certificate (curlcode 60)?
Description Due to a problem in the Quartus® Prime Installer Software, you might see the error message shown below when you click Download & Install. This happens because the certificate bundled with the Quartus® Prime Installer Software is no longer accepted by the Altera® Content Delivery Network (CDN). As a result, secure downloads initiated during the installation process cannot be verified using the outdated certificate. The issue impacts the Installer for the following versions of Quartus software: Operating System Quartus Prime Pro Installer Version(s) Quartus Std/Lite Installer Version(s) Microsoft Windows* 23.3 to 25.3.1 23.1std to 25.1std Linux* 23.3 to 23.4 23.1std The KDB workaround provided below applies to the following versions of Quartus software: Quartus Prime Pro Installer Version(s) Quartus Std/Lite Installer Version(s) KDB workaround applies to 24.3 to 25.3.1 24.1std to 25.1std Note that for all other affected versions not covered by the KDB, you cannot use the installer workaround and must download Quartus software package files individually without using the installer. Separate packages can be found in the Individual Files tab of the Quartus Software Download pages. Resolution To work around this problem, follow these steps: 1. Download and unzip the cacert.zip, which contains the cacert.pem certificate file. 2. Specify the new certificate using one of the following methods: i) Command Line Interface (CLI): Open a command prompt or terminal and run the installer with the--cacert option, pointing to the new certificate file. Windows*: qinst_<version>.exe -sp"--cacert <full path to cacert.pem>" Linux*: qinst_<version>.run -- --cacert <full path to cacert.pem> ii) Graphical User Interface (GUI): - Open the Quartus® Prime Installer, navigate to Settings, locate the CA Certificate Path, and specify the full path to the cacert.pem certificate file. - Then, click Apply > OK. This problem is scheduled to be resolved in a future release of the Quartus® Prime Installer Software.Why does the text overlap in the ALTPLL IP Parameter Editor?
Description Due to a problem in the Quartus® Prime Standard Edition Software version 25.1, you might see that the text overlaps in the ALTPLL IP Parameter Editor on the Windows* Operating System. This prevents the ALTPLL IP from being instantiated. This problem does not occur in the Quartus® Prime Standard Edition Software version 24.1 and earlier. Resolution To work around this problem in the Quartus® Prime Standard Edition Software version 25.1, download and install the patch below: This problem is scheduled to be resolved in a future release of the Quartus® Prime Standard Edition Software.
Error: TBBmalloc: skip allocation functions replacement in ucrtbase.dll: unknown prologue for function _msize
Description Due to a problem in the Quartus® Prime Standard Edition Software version 24.1 or earlier, you may see this error message when generating Altera® IP on the Windows* 11 OS (Operating System). Resolution To work around this problem, follow these steps: Go to This PC, right-click, and select Properties. Click Advanced System Setting. In the Advanced tab, select Environment Variable. Under System variables, create a new variable with the name TBB_MALLOC_DISABLE_REPLACEMENT and value as 1. Click OK and restart the Quartus® Prime Software.Why does Linux report "DMA engine initialization failed" error when EMAC uses GMII interface?
Description When supporting GMII interface for HPS EMAC, there are three clocks exported to FPGA: emac_tx_clk_i(input), emac_rx_clk_i(input), emac_gtx_clk(output) The Linux would report below error if the emac_tx_clk_i clock is not connected correctly: ...... [ 4.291414] socfpga-dwmac ff802000.ethernet: Failed to reset the dma [ 4.297785] socfpga-dwmac ff802000.ethernet eth1: stmmac_hw_setup: DMA engine initialization failed [ 4.306806] socfpga-dwmac ff802000.ethernet eth1: stmmac_open: Hw setup failed ...... Resolution Besides connecting the emac_rx_clk_i(125MHz) for GMII, the emac_tx_clk_i also needs to be connected correctly (2.5MHz or 25MHz), although it is not used in GMII mode. The emac_tx_clk_i requirement information has been added in the HPS document beginning with version 21.2.Error : FLEXlm version of vendor daemon is too old
Description In the Questa* FPGA Edition simulator and Questa* FPGA Starter Edition simulator version 2024.1, you might see this error or the following error if you are using the MGCLD daemon v11.16.4 “Unable to checkout a license. Make sure your license file environment variable (SALT_LICENSE_SERVER, MGLS_LICENSE_FILE, LM_LICENSE_FILE) is set correctly” Resolution To avoid this error, upgrade to the Siemens* Flexlm (SALTD) daemon v11.19.5 Download the daemon from the download page There is a change to the Siemens* License in v11.19.5.0. If you’re running a floating license server for Siemens* licenses, manually change the VENDOR daemon line in the license file from mgcld to saltd, for example: VENDOR saltd <path to saltd> Note: Do not change any of the INCREMENT lines. Leave the INCREMENT lines with the original vendor daemon name (mgcld).Can a 9-transceiver channel Arria V GT device support an Rx only channel that already has four 6.144-Gbps duplex or Tx channels?
Description No, a 9-transceiver channel Arria® V GT device cannot support an Rx only channel that already has four 6.144-Gbps duplex or Tx channels. Due to a bug in the Quartus® II software versions 13.1 and earlier, the Fitter will not produce an error message for the configuration above. Resolution This problem is fixed in Quartus II software version 13.1 and an error message is produced with the above illegal configuration.Error-[XMRE] Cross-module reference resolution error
Description Due to a problem in the Quartus® II Software version 12.1, errors may be seen when simulating the PCI Express® Qsys RootPort example design using the autogenerated simulation scripts for the Synopsys VCS tool and the Cadence Ncsim tool. One of the following errors may be seen: VCS ===== Error-[XMRE] Cross-module reference resolution error ../../<variant>_tb/simulation/submodule/altpcietb_bfm_ep_example_chaining_pipe1b.v, 912 Error found while trying to resolve cross-module reference. token 'bfm_log_common'.

Description Due to a problem in the Quartus ® Prime Standard and Lite Edition Software version 19.1 through 24.1, the Nios® II Command Shell utility included in the Quartus ® Prime Software for Windows* is vulnerable to a Current Working Directory (CWD) planting attack. The Linux* versions are not affected. Resolution To work around this problem, replace the “Nios II Command Shell.bat” Windows Batch File located in the <drive>:\<edition>\<version number>\nios2eds\, with the attached file below. This problem is fixed beginning with the Quartus® Prime Standard and Lite Edition Software version 25.1.Error: border: Error during execution of script generate_hps_sdram.tcl: seq: Error during execution of "{C:/intelfpga/20.1/quartus/../nios2eds/Nios II Command Shell.bat} make all 2>> stderr.txt": child process exited abnormally
Description Due to a recent Windows update from Microsoft®, the Nios® II build flow using Windows Subsystem for Linux (WSL) is presenting issues during project compilation and download. Since EMIF generation needs Nios® II to build flow, you may see this error when generating any EMIF IP or Cyclone® V/Arria® V HPS IP with the Intel® Quartus® Prime Standard Edition Software version 19.1 or later versions for Windows. The failure has been identified in computers running Windows 10 Version 1903 and later. Resolution Please first make sure WSL is installed in your Windows (NiosII Software Developer Handbook, 2.1 Installing Windows Subsystem for Linux (WSL) on Windows), then download patches for Intel® Quartus® Prime Pro/Standard Editions which solved a Windows 10 issue (see detailed in here). Please make sure that only WSL1 is installed and not WSL2 which is not supported.
