The SVD corresponds to the chip reference manual, and gives
register/field descriptions for the manufacturer-specific devices (so
not for e.g.NVIC). So the atsam3x8e SVD outputs

atsam3x8e-adc.ads
atsam3x8e-can.ads
atsam3x8e-chipid.ads
atsam3x8e-dacc.ads
atsam3x8e-dmac.ads
atsam3x8e-ebi.ads
atsam3x8e-efc.ads
atsam3x8e-emac.ads
atsam3x8e-hsmci.ads
atsam3x8e-interrupts.ads
atsam3x8e-matrix.ads
atsam3x8e-pio.ads
atsam3x8e-pmc.ads
atsam3x8e-pwm.ads
atsam3x8e-spi.ads
atsam3x8e-ssc.ads
atsam3x8e-sysc.ads
atsam3x8e-tc.ads
atsam3x8e-trng.ads
atsam3x8e-twi.ads
atsam3x8e-uart.ads
atsam3x8e-uotghs.ads
atsam3x8e-usart.ads
atsam3x8e.ads

where atsam3x8e.ads defines types for bitfields and, for example,

   PIOA_Base: constant := 16#400E0E00#;

for device register base addresses; and the others define specific
register definitions for devices.

Not all the generated files compile without error;

   compilation of atsam3x8e-adc.ads failed
   compilation of atsam3x8e-chipid.ads failed
   compilation of atsam3x8e-uotghs.ads failed

and, for the first,

atsam3x8e-adc.ads:525:07: reserved word "in" cannot be used as identifier
atsam3x8e-adc.ads:526:07: reserved word "out" cannot be used as identifier
atsam3x8e-adc.ads:531:15: expecting expression or component association
atsam3x8e-adc.ads:532:07: declaration expected

(the first two are the actual problem). So, work to be done.
