Hi,
I am trying to simulate the Example Instance of the Altera DDR SDRAM Controller
IP Core.
As described in the DDR SDRAM MegaCoreFunction User Guide
I type the following command under Modelsim
to simulate the IP functional simulation model.
set use_simgen_model 1
source example_controller_ddr_sdram_vsim.tcl
When running the tcl script I get error messages that several signals
are not found, for example:
# ** Error: No objects found matching "/DDR_SDRAM_top_tb/dut/local_rdata"
# Executing ONERROR command at macro ./wave.do line 35
What is going wrong ?
One additional question:
What is the difference if I simulate the pre-compiled ModelSim VHDL libraries
or if I simulate with an IP functional simulation model (DDR SDRAM MegaCore
Function UserGuide page 43) ?
Maybe someone has tried to get startet with the IP Core and has some
idea of what goes wrong ...
I am using QuartusII v. 4.1 SP1 and Modelsim Altera 5.8.c
Kind regards
