Hi,

I want to implemen my design on Xilinx Spartan6 FPGA and so using Mentor Precision for synthesis. I want to generate an .edf file and later to P&R. My TCL script has parsed the design files, all the commands look good.

The log file which is generated after running the 'compile' command contains only 1 error message.
# Error: [40008] : HDL analysis failed.

I don't understand what this error means. Other than the line given above, there is no more info on this error. I don't understand what should I rectify to remove this error.

Please advice.
 

I think you should post the synthesis report not one line out of a top level log file. That error is probably a result of something that is reported in the actual synthesis report.
 

Re: [moved] Anyone experienced with Synplify for synthesis?

Hello,
First of all, I am using Synplify tool and not Precision!

I am posting a part of the error report file. My current problem is Synplify is not able find the VHDL libraries that are defined in some top-level blocks. I think that due to this it shows many errors.

My TCL script in which I am using a Xilinx VHDL IP:
Code: 
# Open a new Project
project -new

# Set the target technology, part number, package, and speed grade options.
 # some verilog files are added

# Xilinx VHDL IP

The top-module and many other design files for this IP uses the libraries axi_lite_ipif_v1_01_a, proc_common_v3_00_a, may be others. One can clearly see in the above dir structure that 'axi_lite_ipif_v1_01_a' and 'proc_common_v3_00_a' are directories and they contain many .vhd files.

So my question how do I make my Synplify TCL script aware of these libraries?

Duration simulation, I never compiled the files under dir 'axi_lite_ipif_v1_01_a' and 'proc_common_v3_00_a' directories.

THe reference manual shows something like:
add_file -vhdl -lib {work, my_lib1, my_lib2} files.vhd

But the above command dosent't help. Do I need to compile these additional libraries into 'work'? If yes, how do I do this?

Figured out to some extent why the error was thrown. It was not a problem with the tool.

Basically I had to modify all the VHDL files so that they used 'work' library. Previously custom libraries were used.
A sample of the substitution used is as follows.

Code: 
--library axi_iic_v1_02_a;
--use axi_iic_v1_02_a.iic_pkg.all;
--use axi_iic_v1_02_a.upcnt_n;
--use axi_iic_v1_02_a.shift8;
library work;
use work.iic_pkg.all;
use work.upcnt_n;
use work.shift8;
 

You can use custom libraries, but you need to compile the files into that library and then reference the mapped library in Synplify. I don't recall the exact details (haven't used Synplify for 8+ years). Editing all your code, and perhaps generated IP code, isn't the way to fix this issue.

Yes, I agree with you. But I couldn't easily find a way to do it with Synplify.
Hence this workaround which is not the best solution. But I will look again tomorrow, if I get the solution/TCL command, I'll post it.
 

I moved to best practice.
As mentioned by ads-ee : "You can use custom libraries, but you need to compile the files into that library and then reference the mapped library in Synplify."
I was not reading the command_reference.pdf carefully!

The cmd in Synplify is: add_file -vhdl -lib {mylib, my_lib1, my_lib2} files.vhd

One just needs to see the vhd source files, note what library is being used and then compile the sources into that library library name using the above command.
