dsp builder遇到的错误

cafppla

做FPGA开发时，先在DSP Builser下仿真通过，用Signal Compiler生成了相应的文件，接着在Modelsim下运行.tcl文件报错，其情况如下
# invalid command name "set_global_assignment"
#     while executing
# "set_global_assignment -name "QIP_FILE" [file join $mdldir "Sinout.qip" ]"
sinout是可控正弦信号发生器的文件名
不知道是什么原因。是生成的.tcl文件错误，但是在Simulink下的算法级仿真通过了tcl文件如下set mdldir [file dirname [info script]]

puts "Adding DSP Builder System sin to project\n"

set_global_assignment -name "QIP_FILE" [file join $mdldir "sin.qip" ]

if { [file exist [file join $mdldir "sin_add_user.tcl" ]] } {
        source [file join $mdldir "sin_add_user.tcl" ]
}


# Add an index file for the Librarian
set ipDir "[get_project_directory]/ip/sin/";
if { ![file exists $ipDir] } {
        file mkdir $ipDir;
}
# Reference the file by relative path if possible
if { [file pathtype $mdldir] == "relative" } {
        set mdlIPX "../../$mdldir/sin.ipx"
} else {
        set mdlIPX "${mdldir}/sin.ipx"
}
set ipxFP [open "$ipDir/sin.ipx" w]
puts $ipxFP "<library><index file='$mdlIPX'/></library>"
close $ipxFP
