Merge pull request #1449 from pepijndevos/gowin 
Improvements for gowin support
 2019-11-19 17:29:27 +01:00
Pepijn de Vos 8ab412eb16 Remove dff init altogether 
The hardware does not actually support it.
In reality it is always initialised to its reset value.

- MULT18X18SIO (Spartan 3E, Spartan 3A)
- DSP48A (Spartan 3A DSP) — implemented in terms of DSP48A1
- DSP48A1 (Spartan 6)

whitequark 3c643c57df write_verilog: add -extmem option, to write split memory init files. 
Some toolchains (in particular Quartus) are pathologically slow if
a large amount of assignments in `initial` blocks are used.
