NGD2VHDL 2.1i - Instance dll0_clkdll does not have generic named 'tperiod_clkin_posedge' (X_CLKDLL)

描述

KEYWORDS: sdf, vhd, modelsim, quickhdl, dll, tperiod_clkin_posedge, simprim,
timing, simulation

URGENCY: Hot

GENERAL DESCRIPTION:

When trying to do a post place and route simulation on a virtex design which
uses the DLL in Modelsim you get the following error when you simulate:

#ERROR: time_sim.sdf(91): Instance dll0_clkdll does not have generic named
'tperiod_clkin_posedge'

解决方案

Three lines must be changed from the following two VHDL simprim files:

1) simprim_Vcomponents.vhd

line 526 reads

tperiod_CLKIN : VitalDelayType := 0.010 ns;

should be changed to:

tperiod_CLKIN_POSEDGE : VitalDelayType := 0.010 ns;

2) simprim_VITAL.vhd

line 1631 reads

tperiod_CLKIN : VitalDelayType := 0.010 ns;

should change to

tperiod_CLKIN_POSEDGE : VitalDelayType := 0.010 ns;

line 1798 reads

Period => tperiod_CLKIN

should change to

Period => tperiod_CLKIN_POSEDGE

After making the above changes you will need to recompile the files.
Please see (Xilinx solution 2561) Resolution 2, the VHDL SIMPRIM
section.
