Virtex CLKDLL timing simulation in MTI: WARNING[1]:No default binding for component : "x_clkdll". ( Generic "tperiod_clkin" is not on the entity)
Description
Keyword : clkdll, simprim, modeltech, simulation, service pack 1
Urgency : hot
General Description : When updating Alliance or Foundation with Service Pack 1, the simprim models file (simprim_vital.vhd) was changed.
The x_clkdll model had a parameter changed from tperiod_clkin to tperiod_clkin_posedge.
