WebThe specified construct is not synthesizable and therefore, SpyGlass cannot synthesize the design unit containing that construct. In some cases, the construct is ignored during synthesis.

Web19 Apr 2015 · 1 Answer Sorted by: 1 It is not synthesizable. The number of times that the for loops is not known at compile time. Recall that the for condition has tmp, which is initialized with data whose value we don't know at compile time. In order for this code (or any other) to be synthesizable, the compiler must be able to unroll the loop.

WebThe most fundamental non-synthesizable piece of code is a delay statement. The FPGA has no concept of time, so it is impossible to tell the FPGA to wait for 10 nanoseconds.
