總結(jié)LX110T的板子上跑demo的時候遇到的一些錯誤的解決辦法
前一段時間在玩xilinx送我在跑XUPV5-LX110T，首先跑xilinx給出的XUPV5-LX110T的demo設(shè)計，結(jié)果發(fā)現(xiàn)遇到了一些錯誤但是自己在網(wǎng)上發(fā)現(xiàn)很少有答案，就把自己的一些總結(jié)貼出來：
(1)xupv5_bsb_std_ip時出現(xiàn)了問題，其錯誤描述如下：
[xupv5_bsb_system.ucf(1110)]: NET "xps_iic_0_Gpo_pin" not found. Please
verify that:
1. The specified design element actually exists in the original design.
2. The specified object is spelled correctly in the constraint source file.
IOSTANDARD=LVCMOS33;> [xupv5_bsb_system.ucf(1111)]: NET "xps_iic_0_Gpo_pin"
not found. Please verify that:
1. The specified design element actually exists in the original design.
2. The specified object is spelled correctly in the constraint source file.
make: *** [__xps/xupv5_bsb_system_routed] Error 1
解決辦法：打開xupv5_bsb_std_ip文件夾里面的xupv5_bsb_system.mhs文件，
在其80行的位置，將PORT xps_iic_0_Gpo_pin = xps_iic_0_Gpo, DIR = O, VEC = [31:31]注釋掉(即在前面加上#即可)或刪除。
在其551行的位置，將 PORT Gpo = xps_iic_0_Gpo注釋掉(即在前面加上#即可)或刪除。
保存該文件。
然后打開xupv5_bsb_std_ip文件夾里面的xupv5_bsb_system.ucf文件
在其1110行和1111行的位置，將Net xps_iic_0_Gpo_pin LOC=AK6; # DVI_RESET_B
Net xps_iic_0_Gpo_pin IOSTANDARD=LVCMOS33;兩行刪除或者注釋掉。
保存該文件即可。

Done!
看到了這個問題，首先要學(xué)會自己找，上面明顯提示是lwip出錯，我們看一下datasheet就會發(fā)現(xiàn)： lwIP provides an easy way to add TCP/IP-based networking capability to an embedded systemlwip_v3_00_a in EDK provides adapters for the xps_ethernetlite and xps_ll_temac
Xilinx? Ethernet MAC cores, and is based on the lwIP stack version 1.2.0. This document
describes how to use lwip_v3_00_a to add networking capability to embedded software. 我們知道了它的作用，那就找吧，反正，xilinx里面是以mhs和mss文件為主線，那就行動吧
解決辦法：在mss文件里找到# BEGIN LIBRARY
PARAMETER LIBRARY_NAME = lwip
PARAMETER LIBRARY_VER = 3.00.a
PARAMETER PROC_INSTANCE = microblaze_0
PARAMETER api_mode = SOCKET_API
END
將其注釋掉或者刪除。

解決辦法：到桌面右鍵單擊我的電腦，選擇屬性，再選擇高級這一欄，單擊環(huán)境變量，在新彈出的環(huán)境變量對話框下，單擊系統(tǒng)變量的新建按鈕，輸入變量名：CYGWIN
在變量值中輸入：nontsec，單擊OK，重新啟動XPS，重新編譯即可。

解決辦法：This error can be safely ignored as it is being generated incorrectly. The project will implement.
官方給出的答復(fù)是忽略這個錯誤。

解決方案：官方給出的解決方案是忽略warning，對結(jié)果不影響。
(6).ERROR: 1 constraint not met.
PAR could not meet all timing constraints. A bitstream will not be generated.
To disable the PAR timing check:
1> Disable the "Treat timing closure failure as error" option from the Project Options dialog in XPS.
OR
2> Type following at the XPS prompt:
XPS% xset enable_par_timing_error 0
解決辦法：在XPS的project菜單欄選擇project options中選擇hierarchy and Flow將Treating
timing closure failure as an error前面的√去掉即可。

解決辦法：打開你的工程，在system assembly view的界面下，切換到ports欄下，將fpga_0_DDR2_SDRAM的下拉框中，找到相應(yīng)的的項，選中相應(yīng)的項就可以。
