FPGA Central

I am a newbee in verilog.

I want to know what is significance of trireg and how we can relate it
to real time. What it exactly in Hardware. How we can we use it. Or is
it just for verificaiton.

Thanks in advance

It generally represents a net with enough capacitance that it can
maintain a value even when not actively driven, at least for a limited
time. This is how a DRAM memory cell works, for example. It is not a
verification construct, but a low-level hardware modelling construct.
It could also be used to abstractly represent the presence of active
"bus-keeper" hardware on a net, though I don't know whether anyone
would actually use it for that.
