Is it possibe to request low‐level Oneᴀᴘɪ or OpenCl language extensions ?

In the C analogy using ʀᴛʟ would be equivalent to using a plain .asm file where in .asm you have to care if you use a register or memory which can be handled automatically with a asm/interstic statement. In the ꜰᴘɢᴀ case, this means you still have to clock manually the design.

So this is lower level.

Also, as far I understand, Verilog/ᴠʜᴅʟ code can’t use Sycl code…
