clocks in extracted timing libs

[honey13]

Hi all,

I am using pt for STA. In my design there is one Analog phy, i was provided an .lib file of the hard macro. During my sta i read that file using read_lib.
But the clocks that were in the phy are not available to my current design.

Do I need to redefine that phy clocks in my design? Is there any other approach to read the extracted timing models. My script is as follows:

set link_library tcbnxxx (&other libraries)
read_verilog temp.v
read_lib analog_lib.lib (hard macro)

Warning: Line 32715, Cell 'MADEF', There is a sequential timing arc with the
clkin1 non-clock pin for a related_pin attribute. (LBDB-30)
Warning: Line 32757, Cell 'MADEF', There is a sequential timing arc with the
clkin2 non-clock pin for a related_pin attribute. (LBDB-30)

clkin1 and clkin2 are the clocks in hard macro, do i need to define them again when i am integrating that phy into my design.

Provided .lib file is also generated by pt

Someone help me plz

Why does the warning say that clkin2 is a non clock pin?? Did you check the attribute on that pin to make sure that it is defined as clock.

Hi Jeevan,

I resolved that Warning. But still i am not able to get the clocks those are in .libs to my current design. Do i need to redclare them again? How i can make those clocks available to my design.

I dont think you need to define the clocks again. The clocks defined must be taken by the timer.
