Compiling and Elaborating Your Design

Note:

• 64-bit machines have more capacity than 32-bit machines, but

there is a performance trade-off.

• The process of compiling on a 64-bit machine and simulating the

executable on a 32-bit machine, generally known as Cross-

compilation is not yet supported.

• The 64-bit compilation and 64-32-bit cross-compilation processes

are not available on all platforms, and not all features and

capabilities of VCS work with them. Specific requirements can

change with each release so check this information in the VCS

Release Notes ($VCS_HOME/Doc/ReleaseNotes).

• You can include PLI code in either the 64-32-bit cross-compilation

or full 64-bit compilation processes. PLI code compiled with gcc

usually works fine without any restrictions. Do not forget to compile

the PLI code in 64-bit mode to use it with VCS MX for 64-bit

compilation.

Identifying the Source of Memory Consumption

Before running a 64-32-bit cross-compilation or full 64-bit compilation

process, there are some steps you can take to identify and possibly

solve a memory consumption problem.

If VCS encounters a memory problem during compile-time or runtime,

it typically returns one of the following error messages:

Error: out of virtual memory (swap space)

(v2ss1_16384x64cm16_func.v line 1053458)

Error: malloc(1937887600) returned 0: Not enough space
