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.

Marcin Kościelnicki 7a9081440c xilinx: Add simulation models for MULT18X18* and DSP48A*. 
This adds simulation models for the following primitives:

- MULT18X18 and MULT18X18S (Virtex 2*, Spartan 3)
- MULT18X18SIO (Spartan 3E, Spartan 3A)
- DSP48A (Spartan 3A DSP) — implemented in terms of DSP48A1
- DSP48A1 (Spartan 6)
