Why is the input register not registered in the negative input pins, rx_in[*](n) of the ALTLVDS_RX megafunction?
Description Due to a problem in the Quartus® Prime Standard Edition Software version 23.1 and earlier, you might see that the input register is not registered in the ALTLVDS_RX megafunction's negative input pins, rx_in[*](n). This is because the synthesis attributes "LVDS_RX_REGISTER=LOW" and "LVDS_RX_REGISTER=HIGH" are not assigned to the register in the Low-voltage differential signaling (LVDS) receiver interfaces. Resolution To work around the problem, add the following assignments in the Quartus® Settings File (.qsf): set_instance_assignment -name LVDS_RX_REGISTER LOW -to "altlvds_rx:ALTLVDS_RX_component|altlvdsrx_lvds_rx:auto_generated|altlvdsrx_lvds_ddio_in:ddio_in|ddio_l_reg" set_instance_assignment -name LVDS_RX_REGISTER HIGH -to "altlvds_rx:ALTLVDS_RX_component|altlvdsrx_lvds_rx:auto_generated|altlvdsrx_lvds_ddio_in:ddio_in|ddio_h_reg" This problem is currently scheduled to be fixed in a future release of the Quartus® Prime Standard Edition Software.Is there a known issue with simulating the Cyclone® 10 FPGA LP PLL IP using Verilog?

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 As a result, secure downloads initiated during the installation process cannot be verified using the outdated certificate.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 Nios® V processor system simulation fail with no print-out message and multiple “x” values along the processor’s signals?
Description This problem may be seen in the Synopsys* VCS* and VCS* MX simulators when simulating the Nios® V processor system generated from Quartus® Prime Pro Edition Software version 23.1 to 23.4, or Quartus® Prime Standard Edition Software version 23.1std This is due to the X-propagation support in the simulators. Resolution To workaround this problem, follow these steps: Switch off the X-propagation feature on the processor core, Generate testbench system from the Platform Designer. Navigate into the Synopsys* simulator directory. $ cd <Project>/sys_tb/sys_tb/sim/synopsys Append -xprop=xpropconfig into the shell script in the vcs or vcsmx folder. For example: USER_DEFINED_ELAB_OPTIONS=”-xprop=xpropconfig” Create a file named xpropconfig in the vcs or vcsmx folder (beside the shell script). Copy the following text into xpropconfig, and change the processor entity name. tree {<Nios V processor HDL entity name>} {xpropOff}; Run the simulator. This problem is currently scheduled to be resolved in Quartus® Prime Pro Edition Software version 24.1 and later.Why does the HDMI Design Example fail to generate when using the Quartus® Prime Standard Edition Software version 24.1?
