提示时出现警告消息
我正在尝试模拟测试台。我没有收到波形，而且在提示时收到以下警告消息。是因为=is警告我的代码没有模拟吗？
** Warning: (vsim-WLF-5000) WLF file currently in use: vsim.wlf
# File in use by: Hostname: ProcessID: 0
# Attempting to use alternate WLF file "./wlftazxa4k".
# ** Warning: (vsim-WLF-5001) Could not open WLF file: vsim.wlf
# Using alternate file: ./wlftazxa4k
run
我还包括我的测试平台，如下所示：
module dec_tb;
reg [63:0] FROM_IF_ID;
reg CLK;
wire [117:0] TO_ID_HMIC;
integer k=0;
inst_decode id(.from_if_id(FROM_IF_ID),.clk(CLK),.to_id_hmic(TO_ID_HMIC));
initial
begin
$monitor($time,"clk=%b, fifid=%b, tidhm=%b",CLK,FROM_IF_ID,TO_ID_HMIC);
$display("qf");
CLK= 0;
FROM_IF_ID[35:32]=4'b1100;
FROM_IF_ID[63:36]=28'b0000_10000_00100_01000_00010_0001;
end
always
begin
#10 CLK= ~CLK;
end
always @(posedge CLK)
begin
$display (" TO_ID_HMIC= %b", TO_ID_HMIC);
FROM_IF_ID[k] =~FROM_IF_ID[k];
k=k+1;
#500 $finish;
end
endmodule
I'm trying to simulate a testbench. I'm not getting the waveforms also i'm getting the following warning message at the prompt. Is it because of the=is warning that my code does not simulate?
** Warning: (vsim-WLF-5000) WLF file currently in use: vsim.wlf

I'm also includng my testbench as follows:
module dec_tb;
reg [63:0] FROM_IF_ID;
reg CLK;
wire [117:0] TO_ID_HMIC;
integer k=0;
inst_decode id(.from_if_id(FROM_IF_ID),.clk(CLK),.to_id_hmic(TO_ID_HMIC));
initial
begin
$monitor($time,"clk=%b, fifid=%b, tidhm=%b",CLK,FROM_IF_ID,TO_ID_HMIC);
$display("qf");
CLK= 0;
FROM_IF_ID[35:32]=4'b1100;
FROM_IF_ID[63:36]=28'b0000_10000_00100_01000_00010_0001;
end
always
begin
#10 CLK= ~CLK;
end
always @(posedge CLK)
begin
$display (" TO_ID_HMIC= %b", TO_ID_HMIC);
FROM_IF_ID[k] =~FROM_IF_ID[k];
k=k+1;
#500 $finish;
end
endmodule

如果这是唯一的消息，则模拟将运行，您可以在指定的备用文件 (
wlftazxa4k) 中找到波浪。如果您想解决问题，以便波形出现在 vsim.wlf 中，请尝试以下几项操作：
vsim.wlf在波形查看器中打开vsim.wlf并重新运行If that's the only message, then the simulation ran, and you can find the waves in the specified alternate file (
wlftazxa4k).If you want to fix the problem so the waves show up in vsim.wlf, here are a few things to try:
vsim.wlfopen in a waveform viewervsim.wlfmanually and rerun我也有这个问题。事实证明，我的 vsim 文件所在的目录已满（学校分区，600mb 允许空间）。清除了我周围的一些旧文件后，该程序运行良好。
I had this problem also. As it turns out, the directory that my vsim files were located in was full (school partition, 600mb allowed space). After clearing out some old files i had lying around, the program worked fine.
您的测验：
quit -sim您可以删除 modelsim 创建的缓存文件。
Your your quiz:
quit -simYou can remove cache file create by modelsim.
