It has a hard-IP core block encompassing the PowerPC processors, 622 Mb/s to 6.5 Gb/s serial transceivers, tri-mode Ethernet MACs, dedicated DSP slices, source-synchronous interface blocks, and high-speed circuitry in its clock management. A standard Virtex-4 FPGA building block improves the...
These Verilog models are further synthesized into the gate-level netlist. IBIS IBIS is the standard for describing the analog behavior of buffers of the digital IC’s pins (input, output, and I/O buffers) in plain ASCII-formatted text (behavioral model) without revealing the underlying circuit...
There are synthesis tools that understand tri-state buffers to build tri-state busses but that is for ASICs, not for FPGAs. Now, of course, to simulate in your behavioral testbench it is ok to do such things. So if you have a weak pull-up on your PCB, you can use tri, trireg...

This internal error is scheduled to be fixed in the future release of the Intel Quartus Prime software by issueing an error message instead of internal error. Have you tried to change the design so that the Tri8 symbol used in TriTest.bdf matches the...

O.K. the problem was an old custom generated tristate component. It is part of a component which was generated long time ago in block editor, but as it is still working, it is still in use. By the way I found out that in Quartus Prime Pro 19.2 it is no m...
