Timing Models; here Transport

[Thomas K. Balthasar]

Hello,

I'm a student and have to learn VHDL. In some lectures at university I have
already learned the difference between the transport and the inertial timing
model. Now I try to understand some given VHDL code and there is a signal
assignment with transport but without any delay argument. I tried to find
out something in the internet but I do not find any answer what this could
be. Is there a difference between the two following code lines:

y <= dff_out;
y <= transport dff_out;

It would be very kind if you would answer this probably simple question...

Thank you in advance
Thomas

Dear Friend,
This answer is in any VHDL text. Get used to digging around books for
answers if your serious about engineering.
