quartus和modelsim之间的大坑

唉,人生何其多坑

[TOC]

因为解决bug的时候没有截图,所以合并了一些忘记的,大家对号入座吧

BUG1

The ModelSim - Intel FPGA software comes packaged with precompiled simulation libraries. Do not compile simulation libraries if you are using the ModelSim - Intel FPGA software.

BUG2

Cannot launch the ModelSim software because you did not specify the path to the executables of the ModelSim software.

BUG3

Nativelink TCL script failed with errorInfo: Invalid user compiled directory

这是因为我们要用的是modelsim-intel,而不是modelsim.所以这个bug会在两个地方出现:

错误设置编译器为modelsim,解决方法:
导航栏/assignment/setting/EDA Tool Setting

顺道看看下面的simulation的路径有没有错误就好了
错误设置引导栏/tools/launch simulation library compiler,解决方法
第一步:不管怎样,先用modelsim的正确路径填入executable location
第二步:一定要修改output directory 为正确合法路径(别问我为什么知道,哭)
第三步:Start Compilation ,虽然还是会报错,但是output directory保存下来就可以了
第四步:正常rtl simulation就可以用了.

BUG4

以下为modelsim

Error: (vsim-3033) /home/heweibao/project_fpga/altera/ip/add.v(91): Instantiation of ‘altmult_add’ failed. The design unit was not found.

这是因为没有加库,可以在:simulate->start simulation
design选自己要仿真的,然后点libraries,选自己用过的ipcore

BUG5

Error (suppressible): (vsim-10000) /home/heweibao/project_fpga/altera/ip/add.v(154): Unresolved defparam reference to ‘ALTMULT_ADD_component’ in ALTMULT_ADD_component.input_aclr_a0./# Time: 0 ps Iteration: 0 Instance: /helloworld/U1 File: /home/heweibao/project_fpga/altera/ip/add.v
