AR# 51888

Description

I am doing an I/O Planning project and receive the following DRC error:

"The DIFF_HSTL_II_DCI_18 I/O standard is not supported for bankType Dedicated in bank I/O Bank: 4 (Dedicated). Move the following ports or change their properties: my_port_p[0],..."

I have checked the Virtex-5 product device guide and it appears that the DIFF_HSTL_II_DCI_18 I/O standard should be supported in this bank.

Is the device guide or the DRC incorrect in this case?

Solution

The PlanAhead 14.2 DRC tool incorrectly flags a DIFF_HSTL_II_DCI_18 I/O standard as not supported in Virtex-5 devices.

This issue has been resolved in the 14.3 PlanAhead tool.
