FIR IP configured for Interpolation
Why does my Altera FIR IP, configured for interpolation by 80, produce the expected outputs when I provide 3 input samples, but fail to produce the expected behavior when I provide 10 input samples? In this case, the FIR IP keeps tready asserted high, but only generates 4 valid outputs. What could be causing this behavior? I am simulating this in Quartus Prime Lite Edition.RTL Simulation fails with: couldn't execute ip-setup-simulation: invalid argument
Hi , Error: Failed to run ip-setup-simulation: couldn't execute "c:\altera_pro\26.1\quartus\..\vds\bin\ip-setup-simulation": invalid argument I have been facing this issue since morning, unable to run the simulation, yesterday it was working fine. Even tried regenerating IP files also today, but got the same error. Any help is appreciated. Regards, Sai@2403RTL Simulation fails with: couldn't execute ip-setup-simulation: invalid argument
Hello, I am using Quartus Prime Pro Edition 25.3.1 on Windows 10/11. RTL simulation fails immediately with the following error: Error: Failed to run ip-setup-simulation: couldn't execute "ip-setup-simulation": invalid argument Error: Simulation flow failed Error(23031): Evaluation of Tcl script c:/altera_pro/25.3.1/quartus/common/tcl/internal/nativelink/qnativesim.tcl unsuccessful Additional stack trace: Simulation TCL script failed with errorCode: 1 (procedure "iputf_call_script_gen" line 1) invoked from within "iputf_call_script_gen $spd_file_list" I already checked the following: - Same error occurs for all projects - Same error occurs in Quartus Pro 25.1 and 25.3.1 - Same error occurs after deleting db/, incremental_db/, simulation/ folders - PATH conflict removed (only one vsim exists in PATH) - `vsim -version` shows: "Questa Altera FPGA Edition-64 vsim 2025.2 Simulator" - `where vsim` returns only: C:\altera_pro\25.3.1\questa_fe\win64\vsim.exe - `Generate Simulator Setup Script for IP` also fails - IP regenerate fails with: "Failed to retrieve Quartus project IP search paths" I also noticed that Quartus reports: "Questa Altera FPGA Edition simulator is not supported for simulation library compilation." Questions: 1. Is Questa Altera FPGA Edition (questa_fe) unsupported for Quartus Pro 25.x NativeLink RTL simulation? 2. Is this a known issue with ip-setup-simulation or qnativesim.tcl? 3. Does Quartus Pro require Questa Intel FPGA Edition/full Questa instead of questa_fe? 4. Is there a workaround besides manually running Questa simulation scripts? Thank you.
Licencing error for Questa - Altera FPGA Starter Edition 2025.2 (Quartus Prime Pro 25.1std)
Hello, I have the following error window show up after trying to launch Questa. I have downloaded the license, and created a system variable as shown in the other picture. I also tryed following solutions in similar isues discused here, but to no help.

Questa-sim waveform- How to export to CSV?
I am using Questasim for doing waveform debug. I want to dump current waveform as CSV to apply some analytics on it. When I go to FIle > Export option "waveform" option is greyed out and is not available. I see "Image" option which I dont want; and "VCD" option is also greyed out. please help me on how can i export waveforms I see into CSV format.
Questa on QPP 26.1 not supported on Ubuntu 24.04?
Hello, I'm running into the following error when trying to run a simulation using Questa Starter Edition as part of QPP 26.1 on Ubuntu Linux 24.04: ** Fatal: (vsim-3828) Could not link 'vsim_auto_compile.so': cmd = '/opt/altera_pro/26.1/questa_fse/gcc-10.3.0-linux_x86_64/bin/g++ -shared -fPIC -B/usr/lib/x86_64-linux-gnu .... There are many linker errors that follow, so it seems there are library incompatibilities. I have attached the QPP 26.1 SW Support Matrix, and I see that Questa isn't supported on Ubuntu 24.04. Before I start trying to fix this problem myself, I would appreciate learning about known workarounds or plans to issue a patch, so Questa wll be supported with Ubuntu 24.04. Note that I have found some old stack overflow and forum posts about deleting the Questa local libraries. Thank you.
