Modelsim - SDF incompatibility

Hi,

I am using Modelsim to simulate placed-and-routed Xilinx design. I have noticed that in some cases iopath from sdf is being treated as a transport delay and in some other as inertial delay, although the type of the cell is the same (for example, x_buf_pp). Could someone tell me why is this happening and is there a way to change it?

Thanks in advance!

Hi,

I am using Modelsim to simulate placed-and-routed Xilinx design described in VHDL. I have noticed that in some cases iopath from sdf is being treated as a transport delay and in some other as inertial delay, although the type of the cell is the same (for example, x_buf_pp). Could someone tell me why is this happening and is there a way to change it?

Thanks in advance!
