hi,i have created my custom instruction hardware and created a nios system, system generation was successful but the Quartus II compilation (after system generation) was unsuccessful with displaying an error message as "Error: Project too complex: hierarchy path is too long". so please let me know the solution as soon as possible. thanking u in advance
--- Quote Start --- Try making the hierarchy path shorter. --- Quote End --- You can give more clarification because I have almost the same problem :confused:
If I get it right, you can break down your combinational path into chunks, so along the way, the data is registered. What is happening is that you're expecting the device to do lots of work in one clock cycle, which is apparently not able to!
I have the feeling that kitgath is a spam link posting spider robot.Basically save your project is a directory path with less letters and it should be fine. In example: Use: C:\Project\Custom Nios Instead of: c:\users\john\Documents\projects\schooll projects\2010 Mai\good one\FPGA\Altera Quartus\Tests\I hope this one works\Custom Nios
I recently came across this cryptic error when I had a module within a module that had the same name. It took another pair of eyes to realize my problem.If you see this error, be sure to check the naming of your modules for duplicates.
This is a Windows* OS/file system issue.The cause is directory paths on the drive is longer than 255 characters (including spaces).There's a lot of additional softwares which can fix this problem like Long Path Tool.PathTooDeep.com Long Path Tool can simplify and probably end your problems in unlocking, managing and renaming files that appear to have a long filename. I hope that it will help you! Good luck! Cheers!
I accidentally was naming my qsys project the same as the top level module.It produced the same error. Example: module some_name
