Thanks for your reply.
So, the sentence below is not right? Because a task or function represents the behavior of a single piece of hardware can also be automatic?
• If a task or function represents the behavior of a single piece of hardware, and therefore is not re-entrant, then it should be...
I think that, when the function is implemented into hardware in multiple locations, the function is called for multiple times at the same time. So, the function should be re-entrant. Do I misunderstand it?
Do you mean the function or task representing hardware should be automatic?
The...
•If a task or function is to be re-entrant, it should be automatic.The variables also ought to be automatic, unless there is a specific reason for keeping the value from one call to the next. As a simple example, a variable that keeps a count of the number of times an automatic task or function...
what's the difference between "Manual Override" and "Manual Clock Switchover" in C4
what's the difference between "Manual Override" and "Manual Clock Switchover" in Cyclone IV?
I know that "Manual Override" is used in Automatic Clock Switchover mode.
However, as far as I am concerned, the only...
This image comes from Altera AN433.
As we can see, AN433 requires to constraint the Opposite-Edge Capture Center-Aligned Input with multicycle and false path exception. However, in my opinion, we just have to constraint that with false path exception which would remove the analysis of same-edge...
Thank you.
Gernerally, I use the set_clock_latency to set the latency of the clock of FPGA.
Do you mean that I have to set the latency of the clock of external device?
Thank you for your reply.
I have read the on the "set_input_delay" on "Constraining Designs for Synthesis and Timing Analysis: A Practical Guide to Timing Analysis" book.
But I still have a doubt on that.
As we can see, the input delay includes the source latency without source_latency_included.
what does these sentence mean?
Input delays can already include clock source latency. By default the clock source latency of the related clock is added to the input delay value,but when the -source_latency_included option is specified, the clock source latency is not added because it was...
