This article examines coverage models for the “real” datatype through actual analog devices modeled using SystemVerilog-Real Number modeling devices we used are phase-locked loops (PLL), analog-to-digital converters, and digital-to-analog converters but could be any modeled analog device. The ar...
I am designing pre_emphasis filter for speech recognition system, when I simulate the module in ModelSim it work and give the right output, but I couldn't compile it in Quartus II because real variable data type values are not supported in verilog Quartus II. This is the pre_emphasis fil...
The missing support of real data type is common to a number of Verilog synthesis tools, not just special to Quartus. The structural differences between the languages may be reason, I don't know exactly. I'm also not sure, if the extensive support of real compile-time operations i...
For a system modeling task with sytemverilog, I have various blocks that have outputs of type "real". To match the hardware being modeled (an analog circuit), these outputs need to be connected together. Only one of these blocks would have valid outputs at one time, the others would have...
I have real variable as input to a module and in the instantiation of the module, I have the connected the real variable itself. But still I don’t see the effect of it, when I try to display the same in module. I know in verilog we can’t pass real type as ports ,but in syst...

given data type. For example, consider a case where you would expect the value of the sine wave to be –1 at π. Because the lookup table value at that point must be calculated, the block might not yield exactly –1, depending on the precision of the accumulator and output data types...
FPGA which processes video data was designed with Verilog-HDL, and it can accommodate various resolutional videos. The stereoscopic image is configured by two methods which are side-by-side and up-down image configuration. After the left and right images are converted to the...
